Hallo!

I wanted to install the extension "losungen" (german watchwords)and got:

TYPO3 Fatal Error: Extension key "div" was NOT loaded! (t3lib_extMgm::extPath)

I get this error at backend and frontend now at http://www.jesusbefreit/typo4
How could I solve this??

Greetings, Andreas.

Ugh - just went through this myself when trying to install an online viewer for the manuals. (Still looking for one, BTW.)

You're going to need to go into some FTP App and modify your files to remove that extension from the "enabled" list. I'm pretty sure that you're looking at the Typo3conf folder, "localconf.php" file. Search for:
$TYPO3_CONF_VARS['EXT']['extList'] =

Look for your bad/incomplete extension in this list and delete it. From the sound of the message, you need "div", but don't have it installed, but that seems odd to me.

Hope that helps. I know this can be done through a file edit because I just did the same thing, so you may want to check a couple of files. I recommend FileZilla if you don't have direct access to the server hosting the files - it has a nice "Edit" function available to easily edit the files on the remote server.

Thanks Peter!

I tried and deleted some of the stuff you wrote, had then "Extension key "sv" was NOT loaded!" After all I installed typo3 once again (had not to much content in it)
I see that backup is necessary...
What do I have to backup: the database, and which folders?

Greetings, Andreas.

Backups are always a good idea - the folder containing the TYPO3, TYPO3 conf, etc would be what I'd back up. I'd also get regular backups of the MySQL Database.

However, in this case, you need to get through the file just to remove those values. A full backup or a full re-install should not be necessary. It basically means that you're trying to load an extension for which you don't have a pre-req or something along those lines.
