Error on saving and adding new content in blocks

Permalink
Hey!
I have a quite wierd problem with two of the sites I'm managing. All in all we have 3 sites at one server, at MeeBox.net, the two sites has been moved from a other server, they both run 5.5.2 (have tried to upgrade to the latest version, but still got the same issue). So, to the problem. Whenever I try to edit a block (or add a new one - whenever I press "save"), an error message box appears, but there ain't no real error message. The content of the error box is more or less a textual representaion of the whole page. It isn't possible to save or add new content, so I close the editor. After closing I somehow get logged off. Does anyone have an idea of what is going on?

If anyone feel like playing aroud and see what happens

I suffered this before C5.5, can't remember how I fixed it!

What you could do is try taking out all javascript, see if the site works without any.

Then replace one javascript at a time and see if any kick in errors.

Hey all,

I got it figured out - or well, I found a fix.
I took a backup of the whole site. Then reinstalled C5 on the server.
After this i just moved all the old folders (except the Concrete) back on the server, and pointed the config/site.php back to the old database :)
