I did exactly that ... from 1.25 to 1.26 and I forgot that the skin is
not included in the composer json ...
thanks for reminding me.
Works not after a manual update. Thanks

Vector is still maintained, and used on Wikimedia
wikis. But we only
guarantee compatibility with the same MediaWiki version – if you have
a Vector skin for e.g. MediaWiki 1.25, it may not work with MediaWiki
1.26. You probably just need to upgrade your Vector skin, same as you
would upgrade an extension.
