    Hello,

    My staging site stopped loading with the WP “There has been a critical error on this site.” message. I edited wp-config.php on the staging site to enable WP_DEBUG and create the debug.log file. Here are the results.. I’m using Windows Server 2019, IIS 10 and php

    FYI dropping back to php 7.4.19 fixed this error.

    Hello @paullheinrich

    Hope you are having a great day! Thanks for reaching out.

    From the debug log, we can see that the fatal error was thrown from the class-wp-hook.php file, which is a core WP file.

    We are glad that you already figured out that it’s a PHP issue and were able to fix it.

    If anything else comes up, don’t hesitate to contact us.

    Cheers!
