1st Issue
I ran into an issue upgrading to 1.26.2
I could not open MediaWiki:Common.css or MediaWiki:Common.js
I found there is an issue with SyntaxHighlight_GeSHi
Fatal error: Class 'Symfony\Component\Process\ProcessBuilder' not found in
/app/mediawiki/mw/extensions/SyntaxHighlight_GeSHi/SyntaxHighlight_GeSHi.class.php on line
283
I disabled it and resolved the issue
2nd Issue
<div class="toccolours mw-collapsible mw-collapsed"
style="width:60%">
Does not seem to work
Thanks for all your help!
Phil
