PHP 7.4 update breaks admin?
Development and Programming
Dreamhost just updated servers to PHP 7.4 and it seems that my clients admin area is now broken. The user facing site is still working at least, but just can’t access admin cms. Any idea if this was due to 7.4 and if its EE code or something on dreamhost side they have to enable maybe?
can’t tell what version of EE I had installed but it’s been updated within past 4 months. Here’s the errors I get:

Severity: E_WARNINGI had them revert back to php 7.2 and that fixes it. It was using EE 5.3.0 so maybe this has been fixed with a newer version of EE.
EE has supported PHP 7.4 since version 5.3.1 (https://docs.expressionengine.com/v5/installation/changelog.html#version-531). However there’s a possibility that one of the add-ons installed your site does not. I would ensure that you get the latest updates for all your add-ons, then try upgrading again (as always I would suggest going to the latest version of EE6 if possible).
