Hi,
after upgrading to PHP 8.0.25 I get the following error:
Uncaught TypeError: Cannot access offset of type string on string in D:\laragon\www\lindenschule\wp-includes\media.php:779
After deactivating GP Premium, the fatal error no longer appears.
I have additionally migrated the website to my local development environment (laragon), enabled debug and additionally also installed and enabled the Query Monitor plugin. Even there I get the above error.
More information is available in private information.
Thanks and best regards
Hans-Gerd
