Hi everybody,
i just set up a new mediawiki on our webspace. Copied the files to the webspace, followed the installation routine, set up a mysql database, all permissions granted. So far, all this worked out fine.
Now if i try to edit the main page and save anything, it's overwritten by some source code, which leaves the page in chaos. The actual text i entered is also not saved in it, it's just replaced.
This is what it looks like: https://www.dropbox.com/s/rv6r3kcsnmzcyim/wiki_error.jpg?dl=0
Any idea what might cause this? Couldn't find any help searching the web so far. Thanks in advance!
