the error caused by insertScript lines in the https://guildwars.fandom.com/wiki/MediaWiki:SkillTools.js

i'd suggest to find someone who knows fandom-specific js (special:contact is an option, too) and ask to review whole sitewide js: there is old code, document.write that shouldn't be used ever, and probably some more artifacts from 2007.
