I just finished setting up a fresh wiki with the following configuration:
Mediawiki 1.35.6
PHP 7.4.3 (apache2handler)
MySQL 8.0.29-0ubuntu0.20.04.3
ICU 66.1
Lua 5.1.5
VisualEditor 0.1.2
wikimedia/parsoid 0.12.2
Parsoid and Visual Editor were installed through the Mediawiki bundling. I have a wiki with a similar configuration the only difference is Mediawiki 1.35.3, which works perfectly fine. On the wiki with Mediawiki 1.35.6 VisualEditor returns the following error:
Error contacting the Parsoid/RESTBase server (HTTP 403)
Any idea on how I can fix this without updating Mediawiki from 1.35 and downgrading it to 1.35.3? I need to stay on the legacy version of Mediawiki.
