Hi,
I have just updated my site to Joomla 4. But it now gives the error message below. json_decode(): Argument #1 ($json) must be of type string, stdClass given.
If I go to a regular joomla template everything does display normally, so I suspect it's down to the template.
Template is Yamas 2.0.0 with PHP 8.1 (I have also downgraded PHP to 7.4 but then I get other error message. What could be the problem here.
