409 Conflict on Joomla 4 administrator backend Topic is solved

[Pavel-ww]

Update: Opening the admin template on my son's PC works correctly.

None of the browsers on my MacBook Pro are opening the admin template correctly (Firefox, Chrome, Safari)

No Ad Blockers are running on the site (this has caused a similar issue on the backend of another of my websites - specifically with Solidres component).

Hi. When you get an error 409, the first thing to do, check your computer for viruses. Error 409 is a substitution or a conflict of requests, which very often can be the result of Trojan. Based on the fact that there is a problem on your computer only, it can be assumed that viruses are the cause.

@Pavel
No viruses - I run a paid version of Bit Defender and all is tickety boo.

I wondering if it was to do with a J!3/J!4 extension called JCH Optimize, which I have now deleted... Here's a bit of their spiel:

...and it's back again...

Getting this error, which is template based...

Loading module from “https://www.themirrorfoundation.org/tmf ... a9d9f91da1” was blocked because of a disallowed MIME type (“text/html”)

This is a standard MIME type isn't it...? It's in the cPanel MIME types list on Hostgator.

Your site is working fine for me on my Intel based Macbook Pro. Is yours Intel based or the new M1 chip?

You could use your browser Developer Tools to see what the Network tab reveals - maybe post a screenshot.

Why are solidres assets present in the login form?

[sozzled]

I'm going to write this one last time and then I will leave this conversation: the OP's MacBook is compromised (most likely infected with malware).

[thellie]

It's Intel-based - MacBook Pro Retina, early 2015.

Screenshot below... I've managed to solve the previous text/html error, by adding text/javascript (js and mjs) into cPanel's MIME types list... it's given me a new error, though.

Not sure why solidres assets are showing - where are you seeing them - in the page source? I would have to contact the developer to find out.

@Sozzled - just in case: I'm not the OP, apologies for hijacking...

Hi. This error is not the cause of the problem, rather it is a consequence. When correcting the problem, I believe it will disappear. Or at least this can be dealt with later. Close this tab and press the button (exactly what @ceford asked to do).

And, I have no problems with your site.

Therefore, all the same, I believe that the reason is in your computer. Paid antivirus is not a panacea. If there is no the virus in its base, then it will not determine it. Antiviruses protect only from already known viruses which are in their base, but not from new ones.

Try another antivirus or several.

-------------

And advice. Bad idea, install the site in the folder. This can lead to problems with paths to files. Create a subdomain and use it for development.

[thellie]

I'm certain you all have a lot more experience and knowledge than I do, and I also agree that no single anti-virus software is infallible (albeit much less infallible than me).

But, to throw a spanner in the works of the virus theory, I have just checked the website on my android phone again, and it is showing the problem (see screenshot).

"Text/html" is wrong.It should have been "text/javascript"

[thellie]

@PAvel @Ceford - I did what you asked and it now shows 6x 409 conflicts (see screenshot). 3 are stylesheet based, and 3 are svg images in the Atum template - forgive my (continued) ignorance, but svg images are vector graphics and presumably would show an image when viewing them. However, all 3 of the svg files in the Atum logo folder (and the 5 in the directory folder above it) show code, not an image (see screenshot 2). Is that correct?

I'm sorry for this continued thread - I wish I could just walk away, but I need to sort this out so I can actually work on my website.

Hi Per,
Yes, I checked the MIME type list in Hostgator's cPanel, and it wasn't in there, so I added it to the list and the error has gone now.

[Pavel-ww]

Ok. But the problem is still on your side, I think . Try to switch between different types of connection, if these are different providers.

Each time, clean the cache on your device before going to the site. Perhaps your provider has some kind of firewall.

Yes it's correct. SVG not the image, but the code. You can open it in any html editor and change colors and ect, directly in code. And you can apply CSS to this making hover effects and so on.

Hi Per,
Yes, I checked the MIME type list in Hostgator's cPanel, and it wasn't in there, so I added it to the list and the error has gone now.

This could make matters worse! My cPanel hosts show application/javascript for the .js extension. There are no text/javascript entries.

[Pavel-ww]

And one more thought from the contrary. Try to turn off the antivirus. Do you use the same antivirus on all your devices? Perhaps your site got into the Web Firewall of your antivirus. If it will work, add your site to exceptions.

[thellie]

@Ceford... Okay, removed the added MIME types

@Pavel... cleaned the caches on both devices but problem remains. Will try the firewall idea asap.

I've looked this up online over the last few months, and a number of people are having the same issue. The advice given most often is to do with Gzip compression, but everyone who has tried the solutions given has failed to solve the issue. I'll have another look on my son's PC this evening... This is only happening on the J!4 website, but all my J!3 sites are fine.

[thellie]

@Pavel
I only have Bit Defender Antivirus, which doesn't include firewall settings

[ceford]

Your Network screenshot is quite interesting. It shows there are 99+ errors and you have filtered the 409 Status codes. I can see the same network requests but with 200 Status Codes. Frustrating, it would have been good to see the Response Headers, which are just out of the screenshot.

I am guessing that the http 2.0 protocol is pushing the content of the requested files but they are not being received by the browser. Have you tried connecting to your site with your Macbook Pro but using a different access point? There could be something in your own router firewall blocking delivery (this is clutching at straws). Have you tried a hard reload (Shift + Reload on Firefox)? I somehow doubt that the problem is virus related. Something else to check - you have .htaccess files in your site root and in each of your joomla sites (I do that too). Check for any conflicts - but I doubt there will be). The intermittent nature of the problem smacks of a timeout issue - request abandoned if not received within n seconds. I have no idea where to start looking for that,

Your case is not related to this problem. If it were the case, then it would be the same for me. But I have no problems with your site on all my devices. Moreover, starting from Joomla 4.3.0 was given a correction for this - read messages after installation. You need to replace the line of code in .htaccess, or delete old .htaccess and rename htaccess.txt to .htaccess if you do not have some your custom settings there.

I think it would be useful if you gave a link so that others can check. I rewrote the link from your screenshot, but I have no right to publish it without your permission.

I am convinced that the problem is on your side, but I no longer have ideas. If I come up with something, I will return and inform about it.

[thellie]

Gave up for a couple of hours... watched P'Tang Yang Kipperbang on [youtube] (great film from my youth)...

...came home, opened up the site - works normally, no errors generated...

@Pavel - I'd already replaced the old .htaccess file over the weekend with the default 4.3.1 file, so no gzip code lines are in there.

Stopped working again this morning.

Found this thread, but it's not particularly helpful aside from showing that it's not just me with the issue...

https://issues.joomla.org/tracker/joomla-cms/38376

This next link partially explains the humans_21909 response... so it could well be an issue with the web host's server. I'm on a shared server plan with Hostgator at the moment, although likely to change to another host since they can't give me an ETA on when my server will get PHP8 (waiting since March 2022)...

Anyone here on Hostgator and NOT experiencing this issue with J!4?

https://help.redsweater.com/marsedit/humans_21909/

I'm buying a plan on Hostinger soon, so will see if the same issue crops up there on a fresh J!4 install.

[ceford]

I am not surprised your problem is back! Something else you could try if you are using cPanel:

In the Security tab there is a ModSecurity button (even on an inexpensive shared hosting account). That leads to a page in which you can configure individual domains, including On/Off buttons. Select Off and see what happens.

I was looking for something like this earlier today, but Hostgator doesn't have the option in its cPanel. I think it's only an option if you have access to WHM.

[ceford]

I am out of ideas, other than the one you have in hand - try another host.

[thellie]

Me too...!

I'll let you know what happens asap... and thanks for all the thoughts and feedback.

(btw, since the earlier post to say it stopped working, it started working again only to then stop once more...)

[ceford]

One last thought: Macbook Pro / System Preferences / Firewall - is it On or Off?

Did you try using your Macbook Pro from a different access point? Son, neighbour, cafe?

Hi
I use the laptop at home, at work, at another place during the day, and sometimes using my phone's personal hotspot, and the issue occurs everywhere.

The firewall is off, I don't think I've ever turned it on

[thellie]

Okay, I've splashed out on a hosting plan with Hostinger. I've installed a fresh J!4.3.1 and updated to 4.3.2

The only extension I've additionally installed is Fabrik 4, as this is the one I need to have PHP 8, and is essential to the work I'm doing. If there are no issues within the next few hours, I'll start adding other extensions, leaving time between each one to see if the issue crops up again. So far, so good...

If the problem doesn't arise, then would it be a host server issue? Either something in/not in htaccess, or possibly to do with the lack of PHP 8?

[thellie]

Update:

I've been running J!4.3.2 with a Gamma 3 pre-release version of Fabrik 4, along with Solidres 2.13.4 for 2-3 days now.

The only other extensions I've installed are Akeeba Backup and Gantry Framework (plus the Hydrogen and Helium templates).

Since opening a new web plan on Hostinger and enabling PHP 8.1, I've had no problems at all. So it's (almost) certainly not an issue with a virus on my Mac, which I always thought was unlikely.

Once the new website is built and fully tested, barring major issues, I'll be advising our board to move entirely to Hostinger from Hostgator.

I think we can close this thread, and summise it's an issue with Hostgator's server..?
