JAuthentication: :authenticate: Failed to load plugin:

[ceford]

You can disable or enable a plugin using phpMyAdmin and looking in the xxxxx_extensions table - see my screenshot - and set enabled to 0 or 1. However, you don't need to worry about that just now because we know the joomla method is tried next. Just plant that line of code in my last suggestion and let us find out whether it returns 1 or 4 or something else or nothing.

Also, try logging with a deliberately bad username and password: what error message do you see?

I realise that I’m invisible (to everyone except the panel of experts). I would dearly love to know what is the exact URL the OP types into the browser to get the error message displayed in the sixteenth post in this topic? Please!

So, in the mrb_extentions table I have a row (record?) called 88, plg_authentication_joomla. This has the value of 1 in the columns enabled, access protected and locked. Does 1 = enabled, true etc?

Yes, as the column names suggest, where an extension has 1 in the enabled column, this means the extension is enabled; 0 in that column means the extension is disabled. We don’t need to discuss what all the other column names mean or what they’re used for at this time.

That’s one way to enable or disable extensions. I agree with @ceford: there’s no need to disable the plg_authentication_cookie plugin … unless there’s a problem with the file system; see next paragraph.

The usual reason people will see a “failed to load plugin” message is because a plugin is enabled in the database but the required file(s) is/are missing in the file system. See https://joomla.stackexchange.com/questi ... tioncookie for some discussion on this situation. If there is no authentication plugin enabled you would get a different error message; there must be at least one authentication plugin enabled and, in this case, there are two.

Everything points to a J! 4.x website with a shonky file system on the XAMPP machine; missing files or files not properly located where they should be.

Thank you webdongle for your reply. Thank you for confirming that 1 = true and 0 = false in the configuration.php file.
The question of which values need updating to '0' still remains unanswered. The values I listed above have neither 1 or 0. So which values in the configuration file should I edit to '0' ? I genuinely do not know, however that may seem to you amazing people that answer these questions.

[sozzled]

Thank you webdongle for your reply. Thank you for confirming that 1 = true and 0 = false in the configuration.php file.

I can't see where @Webdongle mentioned anything about the configuration.php file.

I asked before,

... what is the exact URL [you type] into the browser to get the error message displayed in the sixteenth post in this topic?

[Webdongle]

Thank you webdongle for your reply. Thank you for confirming that 1 = true and 0 = false in the configuration.php file.

Perhaps you need to put your glasses on?

A little pointed but the message may get through … in a month of Sundays …

Anyway, advice about what to do with the database notwithstanding, my conclusion is unchanged:

Everything points to a J! 4.x website with a shonky file system on the XAMPP machine; missing files or files not properly located where they should be.

[Nickinamillion]

Which lines do I need to change in configuration.php?

[Nickinamillion]

Hi, apologies, I did not realise that the book continues on to page 2 now, i had not realised how to turn the page.
Thank you webdongle, I do know the difference between 1 and 2, and i have been wearing my glasses, you are right I do need them.
Thank you Sozzled, I have noticed you now I am on the right page. I need to examine some things and get back to you.

[Nickinamillion]

I disabled all the extensions in the mrb_extention folder and got the attached error message.
Drastic
The exact url is https://localhost/jmla_MrBumble/administrator/index.php
I don't think it is worth pausing this, it is broke and I can get around it.

[sozzled]

Enter this URL in the browser, please:

Code: Select all

localhost/jmla_MrBumble/fpa-en.php

Tell us what happens next.

[Nickinamillion]

Just get a blank screen with that url
I think I will enable all the records in the extension table again, it was a rash move disable them.

[Webdongle]

OK so the fpa won't run on your localhost.

1. What localhost are you using?
2. What php version is it?
3. What version of Joomla are you using?

[Nickinamillion]

XAMPP
PHP 8.1.1
JOOMLA 4 (updated from 3, that may have coursed the problem!)

[Webdongle]

If you have the backup of the J3 site then I suggest

1: Install wamp
1. Set the php to 7.4.x
3. Install your J3 backup
4. Check everything then migrate to J4

[Nickinamillion]

I do not have backups that old. Judge me if you like.
Lets close this thread please!

[Webdongle]

Do you have a backup of your J4 site before it broke?
What was the last thing you did before it broke?

[Nickinamillion]

Thankyou WebDongle, but I have got the access to the important things I needed with this site via the PHPMyAdmin and the file structure. It is also a bit difficult to answer your question because I have not paid much attention to this site for quite a while. I am trough grateful for all the help I have received from everybody., I am truly impressed by your abilities.

[Webdongle]

If your database is not compromised then you can rebuild the files for the 3rd part extensions by installing them into a clean Joomla install. Then edit the configuration.php to connect to the original database.

[Nickinamillion]

I was thinking about that approach. I will do some experimenting when I am not so pressed for time. Though I think if I need any help with that, I would do it in a new thread. That way it would be outlined properly and be easier to understand by onlookers. Thanks for all your help.
