 * Wordpress itself supports PHP 8.1 only as “beta support”. Thus, errors may occur,
   see: [https://make.wordpress.org/core/handbook/references/php-compatibility-and-wordpress-versions/](https://make.wordpress.org/core/handbook/references/php-compatibility-and-wordpress-versions/)
 * However, and I think this is much more likely, the cause may also be a plugin
   you are using that is not compatible with PHP 8.1. What the concrete error is,
   can be seen in the error log in your hosting. If necessary, the support of your
   hosting can help you.
 * Alternatively, you could also enable debugging in WordPress. How to do this is
   described here: [https://wordpress.org/support/article/debugging-in-wordpress/](https://wordpress.org/support/article/debugging-in-wordpress/)–
   also here the support of your hosting can help you if necessary to edit the file
   accordingly.
