Thread:Project:Support desk/Skin.php fatalities/reply (3)

I had the same skins problem until just now. As it happens, the /skins folder was missing from the mediawiki installation. Probably from using 1click installs. Fix: Download the proper version from this site. Extract the tarball find skins folder gzip the folder upload to server and uncompress to your wiki location.

And just like that, skins folder exists. No more "missing Skin.php" error. I just did this and the wiki works perfect now. I know this particular thread is old, but I'm posting this fix for others who may have the same problem, and stumble on this.
