Thread:Project:Support desk/Problem with saving MediaWiki posts/reply

I have been having this same exact problem. I've been fighting with a new installation, trying to make it functional. Creating users is not a problem, but creating pages is... After editing/creating a page and clicking the "Save page" button the screen refreshes and the text editor is back to its original state before any changes/creation happened..

I have done a complete manual re-install of the most recent version of mediawiki. I can't find a solution to my problem...
