you'll need ftp- or better shell access to your installation. 
Then I would suggest you delete the both temp_CACHED... files in the folder
typo3conf. After this you'll have to find the "bad" extension(s) and delete
them. maybe you could try to rename the folder typo3conf/ext to something
like ext_bak. This will disable all local extensions.
If this does not help -> try and error ;-) -> go to the folder typo3/ext and
disable some of the new installed extensions (look at the folder dates) by
renaming or deleting them.

good luck
