[TYPO3-english] Unable to access backend after installing ext Image RealURL

[Morten Kjems]

Hi.

Just installed the extension Image RealURL.

Now I get the following error that seems to be related to this bug:
http://forge.typo3.org/issues/25649

How do I solve this problem?

I can't access the backend but the frontend works fine.

All suggestions are most welcome.
