 * WP Cerber blocks my login ever since I upgrated to Php 7.4, which I updated to
   last week. I got a whole overhaul of the website to update the php, so it could
   use the php 7.4.
 * Everything works but I can’t login to WordPress with it. I get this error:
 * Service Unavailable
 * The server is temporarily unable to service your request due to maintenance downtime
   or capacity problems. Please try again later.
 * Additionally, a 503 Service Unavailable error was encountered while trying to
   use an ErrorDocument to handle the request.
 * If I disable WP Cerber, I can login normally.
 * I followed the directions I found here at [https://wpcerber.com/quickhelp/#4](https://wpcerber.com/quickhelp/#4)
 * I really wish I could REALL erase all memories of WP Cerber from my computer,
   but after the eraser, it still rememberd my old settings somehow.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fphp-login-error-help%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * There should be error messages logged in the PHP error log. That would be a great
   place to start troubleshooting. If you know how to find the error log, post some
   relevant entries here and me or somebody else might be able to help you.
 * 
   Or, if you can modify WordPress files via FTP or the hosting control panel, 
   you could enable debugging by setting the `WP_DEBUG` constant in `wp-config.php`
   which will enable the displaying of error messages on your site.
 * You can read more about debugging WordPress in the documentation: [https://wordpress.org/documentation/article/debugging-in-wordpress/](https://wordpress.org/documentation/article/debugging-in-wordpress/)
 * Another option would be to disable the `wp-cerber` plugin by temporarily deleting
   its directory under `wp-content/plugins/` through FTP or file manager in your
   web hosting control panel.
