Hello,
Unfortunately, I had to update the PHP version from 7.4 to 8.0+ because my hoster discontinued support. Various errors are now occurring in several places. Is the theme fully compatible with PHP 8+? Unfortunately, I can no longer use PHP 7.4.
The changes made in the theme options can no longer be saved. I have recorded a video with the errors that have occurred.
In addition, the admin panel has become very slow. I suspect that this is caused by the PHP errors in the background.
You can find my access data in the private area. I have already carried out all the usual troubleshooting measures (switch zu parent theme and deactivate all plugin) based on your last recommendation without success.
