My Emoticons plugin ended up like this after my host provider upgraded to PHP 8.2:
I also changed to a new theme, but my guess is that it is PHP 8.2 that is the problem. What do you think?
Unfortunately not. It is not compatible with PHP 8.2.
Without WP-Optimize, it works. Well spotted. However disabling the cahce is not an option so I have to disable the Emoticons plugin instead. Is there something you will try to fix?
