After upgrading to MediaWiki 1.37.1, I can no longer use the visual editor. The loading box pops up and then gives me the following error:
Error contacting the Parsoid/RESTBase server: (curl error: 7) Couldn't connect to server
I am not even sure how to diagnose this. I spent about 4 hours on the Google trying to find solutions. None seemed to work or were even applicable. Any help would be appreciated?
I am running:
Ubuntu Server 20.04.3 as a VM
Apache 2.4.41
PHP 7.4.3
MariaDB 10.5.13 (not local)
