Thread:Project:Support desk/Error running the update script

So I'm not the most savvy person when it comes to this sort of stuff, but I've made due in the past. But when things go wrong, I typically am at a loss. Case in point:

I've got a wiki http://mafia-town.net/wiki/index.php?title=Main_Page PHP version 	5.4.31 MySQL version 	5.5.37-cll

Now, I installed this wiki about two years ago at version 1.20.6, using Softaculous via my cpanel. When a new update came out for my MediaWiki installation shortly thereafter, I went to Softaculous to update. I ran the updater, and was prompted to navigate to run the update script. I selected my language, and hit next... and the screen went white. There was no option to proceed with the update. My entire wiki was unresponsive, too. All empty white pages, no content, no titles, no logo, no nothing. (Much like it is at this moment, if you navigate to my wiki right now).

At the time, I just restored my backup and opted not to really do anything about it. I looked into it a bit, but never could figure it out, so I just kept an outdated version for a while. That is until now...

Suddenly, the content of my wiki went missing. The pages were still there, the titles were still there, but no content. When I click to edit a page, the content shows up ready to edit. I googled my issue and found: http://www.mediawiki.org/wiki/Manual:Errors_and_symptoms#You_see_a_Blank_Page (In the section called "All pages have no content, but when editing a page the wiki text is there.") The fix? Update your wiki!

However, the same issue occured. I again restored a backup and tried to perform an update manually (as per http://www.mediawiki.org/wiki/Upgrade). I downloaded the files, uploaded them to my server, unzipped them, added the files from the old install it says I need to move, renamed it to the old pathway name, and went to run the update script. Aaannndd... white pages. Everywhere. I can't seem to run an updater at all.

The recommendation to rename .htaccess seems to be a different issue. So my question is can you help little old me fix this and update my wiki so that we have content on it again?
