TYPO3 Core

I guess the version of the skin you use is not compatible with the new version of TYPO3.
Edit the file typo3conf/localconf.php and delete the skin from the list of loaded extensions.
Then delete the temp_cached-files and try again.

I just removed from my localconf.php the skin_grey2 , but i stil see the backend empty, i can't access to Tools> db to change the referer index

Then the skin was not the reason for this error.

Go to the install-tool and delete all files in typo3temp/ and subfolders.
Also try clearing your browser-cache.
Btw.: Did you do a "compare" and "update" with the database?

If that does not solve the problem: If you click the link: What exactly do you get then?

Why do you not update to the most current version, 4.2.9?

Ok, i solved finally my problem

The tm_contentaccess extension, was making that my BE wasn't visible into the updated 4.* version.

I removed it, and now i can see the modules, the problem is now i see the Backend like 20 years ago :)

But i supose i can find another extension like tm_contentaccess, to improve the backend skin etc

Thankyou for your replys christopher

Install the extension t3skin.

I remember, that skin_grey2 is even working in 4.2...
So if you like your old design more, install versions of tm_contentaccess (and of the other extensions you need for this skin) which work with 4.1.

Finally: This is no bug in the TYPO3 core and so can be closed.
