Problem with modules for joomla 4

marpe

When I try to paste the module into joomla 4, I get this message: Deprecated: stripos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /home/eoborniki/domains/marpe.eu/public_html/templates/gk_news/html/mod_custom/default.php on line 30
I have a large information service on joomla 3 and I transfer it to version 4 and it's some kind of masax, still some bugs.

Hi marpe

As I understand, you want to override the layout for the Custom HTML module, right? This layout is copied from what template, please?
Can you please share the website where you get the issue? We need to check the layout you want to override to see if there is issue.

Best regards.
