I am not able to replicate the error using PHP 8.0 /8.1, any additional information would be appreciated.
sure. Please check my server configuration and the warning message here https://drive.google.com/drive/folders/1k6bG2NaLXVACyYComFpjaCtgcLmoCaYe. This message appears when I go to wp-admin. Usually it is on top, but in some cases it also appeared in the middle of some configurations.
I am still not able to replicate the error and I am going to need more information, theme, plugins etc.
could you contact me via the Links Page website.
