Hello,

Do you get this problem also with Joomla 3.10, PHP 8 and Themler 559?

I am waiting since Jan. 25 for an answer. The topic 219584 is still open. Nettie, can you push it again to your developer please ?

I'm still working with that error.
I added some programming code to the error404.php template an get the source of the error.
In my case it is triggered by the file ../editor/functions.php in Line 770
if (!array_key_exists($currentTemplateName, $sampleData))

A workaround for me is to stop the program running through this if case by changing the line 6 lines above from
if ($GLOBALS['theme_settings']['is_preview']) {
to
if ($GLOBALS['theme_settings']['is_previeww']) {

This would be overwritten if you load the editor so you have to do it again.
A bad workaround but for me actual the only possibility.
Support is not responding on my request. :(

Since you mentioned that the error seems to correlate with the content, try removing or modifying specific content elements in the template to see if the issue persists. This can help you identify if certain content elements are causing the problem. After that you can access monopoly online and play with me, thanks

Thank you for that hint. Meet us on the BOARDWALK.

An error appeared in the THEMLER template editor (ver 559) for JOOMLA 3.10.11 after switching to PHP 8.0 but only in the BLOG template. The webpage is running fine with no errors.

If I select the Blog Template in theme editor it will redirect me to the page not found (404) template with showing up this error: "array_key_exists() argument #2 ($array) must be of type array stdclass given"

I tried to locate the error. I have exported the theme an I have imported it into the desktop Themler. Unblocked games 76 is a website that offers a large collection of free online games that can be played without any restrictions or blockages Once with content and once without content. Without content it works fine but with content I get an ERROR null - JOOMLA (see image).
It seems that the content correlates with the theme. Fairly unclear if the cause is the content or the theme or both.

Has anyone a guess how I can narrow down the error further?
Is it possible to get some more detailed error description from the themler theme editor?

The error array_key_exists() argument #2 ($array) must be of type array stdclass given indicates a type mismatch. A function expects an array, but a stdClass object is provided.
The error occurs specifically in the Blog Template within the Theme Editor, suggesting a conflict with either the template code, content structure, or PHP 8 compatibility.

I remember that I changed the error404_9.php in the folder templates/THEMENAME/editor/templates and added there some php to get more error information.
