A working installation of mediawiki was corrupted by a user "touching" all files under the dir structure, ending in all files having the same exact permissions, and modify dates. I'm not sure which of the above had caused the wiki to stop working, but in fact - that's what happened.
The mediaWiki is version 1.26 - currently out of support, so I know.
Every single file of the wiki is available, and the dir' structure is indeed intact. The wiki's DB is not longer available. However the images/media (if indeed stored using the DB), are not as critical to the user as the actual page text content.
Is there a way to save this wiki ? I've looked into restoring mediaWiki, but then it's assumed the wiki has been backed up properly, and this is not our case, unfortunately.
