jos-error article not found instead of 404

[rookbears]

I am having an issue with articles not showing up, but found that Efseo was causing some issues, and turned off. Now I get the 404 page. Can't disable redirects and other post had no solution. https://purrfectcompanions.org/cat-news ... ous-events Click on link and get a 404.
Error reporting shows:
Notice: Trying to get property of non-object in /home/purrfe12/public_html/plugins/system/helix3/core/classes/menu.php on line 260

Notice: Trying to get property of non-object in /home/purrfe12/public_html/plugins/system/helix3/core/classes/menu.php on line 263

Notice: Trying to get property of non-object in /home/purrfe12/public_html/plugins/system/helix3/core/classes/menu.php on line 264

Now I am trying to layout a blog layout for event galleries, but am getting an error: "Cannot use object of type stdClass as array" when I try and add a new menu item.
Are these two issues related? I did contact joomshaper on this issue, and they say it is a Joomla issue.
Can someone confirm and help? Can give backend credentials if needed.

Thanks so much

Knowing more about your site and hosting would help us; please use the FPA to help you provide that information: viewtopic.php?f=714&t=793531.

The forum post assistant (FPA) provides details you haven't done, such as Joomla version, and details about your hosting environment (such as PHP version).

The errors mention Helix3 framework, therefore I would start there, and ensure that is up to date. Your site template may use Helix3; try and find an updated version of the template.

[EDIT: ] I visited the link given in your question, and get the web page linked to (not a 404 error). Did you end up fixing the issue?

First time using this. I hope it can assist you. Again, if you need admin login, let me know.
Thank you!

Chatted with Joomshaper and said that there is an issue with Joomla which is causing additional errors with Joomshaper's template code.

One other thing I noticed is that when I go into Extensions | Manage: The "Search Tools" have no dropdown menu for the "Type" (Component, module,plugin, library,etc.) Just shows blank box. I can type within the box and get results, but dropdown menu is gone.

[AMurray]

One suggestion: try setting Protostar as the default template, and see if those errors still show on the front-end.

Otherwise suggest using another Helix3 template such as these:
https://www.joomshaper.com/joomla-templ ... egory/free
(just try them, eliminating possibility that it's your current template).

I am unaware of such issues as mentioned:

Chatted with Joomshaper and said that there is an issue with Joomla which is causing additional errors with Joomshaper's template code

One other thing I noticed is that when I go into Extensions | Manage: The "Search Tools" have no dropdown menu for the "Type" (Component, module,plugin, library,etc.) Just shows blank box. I can type within the box and get results, but dropdown menu is gone.

I think this is a known issue (not sure if it is resolved or not). I tried searching the forum for the posting I know I have seen on this but the forum is timing-out and giving me white-screen-of death.

I've got that same issue, but there is a blank form field above the "type"column. If you type in say "module" or "plugin" or "component", it will still filter the list, it's just not giving you the drop down to select those choices.

One other thing I noticed is that when I go into Extensions | Manage: The "Search Tools" have no dropdown menu for the "Type" (Component, module,plugin, library,etc.) Just shows blank box. I can type within the box and get results, but dropdown menu is gone.

Completely off-topic but, as @AMurray states, it's a known issue with J! 3.8.10. See viewtopic.php?f=9&t=963139#p3529937 (and, later in that thread, there are instructions on how to resolve that problem).

Sorry, can't help with the real issue here: "jos-error article not found instead of 404"

I did change the template to protostar, and still am having the same issue.
The error reads: Notice: Trying to get property of non-object in /home/purrfe12/public_html/plugins/system/helix3/core/classes/menu.php on line 260,263, and 264. It is also showing on all pages.
I am going to try and layout pages differently, and see if that helps.

Trying to add a new menu item, and am getting: "Cannot use object of type stdClass as array" error.
Might this be a part of the issue?

[Some of] the errors/problems you're having seem to point to the Helix template. I don't use any Joomlashine templates myself and, so, I'm unable to guarantee a solution. I've read around the forums that there are solutions provided by Joomlashine to address these matters: search the forum (or the internet more broadly) for "Cannot use object of type stdClass as array" (together with the keyword "Helix" or "Joomlashine") may give you some better tips.

I'm not sure how this relates to the "jos-error" error(s) you're encountering.

Thanks,
Will follow up with Joomshaper, not joomlashine.

Ah, sorry for the misdirection. I don't use Joomshaper products either.

Trust me sozzled, up until today, I wasn't able to find out anything "using Google", but did end up finding that Google Structured Data plugin was causing the issue. I updated it, and alas, error fixed.
With all due respect, my coding skills are not at your level, hence using Joomshaper products for this client.
