What is the best way to make a working copy of the current version of Vector that can then be adjusted?
I wanted to try something similar to DarkVector (a skin based on Vector with just some cosmetic adjustments), but when I duplicate the current 1.37 Vector and change out the skin name in the code and file names, it produces internal errors like this:
Class 'AltVector\SkinVersionLookup' not found. Backtrace: from /var/www/my.wiki/public_html/mediawiki-1.37.2/skins/AltVector/includes/ServiceWiring.php(55) ...
Thanks for any thoughts/suggestions on how best to approach this!
