Thread:Project:Support desk/Lost all content on WikiPage/reply (2)

Currently there is no content displayed on the main page. When you click "Edit" however, you see that it in fact is there. No content is lost; you just cannot see it currently.

Currently you are running MediaWiki 1.16(!), which is old, has known security holes and is not compatible with current setups.

Please upgrade MediaWiki to a current version - most likely this will already solve the problem! See Upgrade for the steps to take!
