Hi
I have a wiki working fine and visible here : https://gestinux.net
It uses an old version of mediawiki (1.33.1) and php (7.2) I know that I must upgrade, but first I have to move it to another server able to run a supported php version.
So, I moved all the files to the new server, accessible by a test subdomain. chmod 755 was applied on all files. Again, it is the same versions of mediawiki and php. I have deactivated my own extensions in LocalSettings.
The result is visible here : https://test.gestinux.net
The layout is wrong, the skin (Vector) looks to be not used.
What am I missing ?
