After installing the bridge I noticed that all of the top buttons links go to option=com_smf, but the ADMIN-button goes straight to the standalone forum still.

I also get a problem with huge error logs in SMF since the mambo side of things still isn't live and all my users are still using the standalone forum. Users using the standalone forum (including myself while I am administrating the forum since that is only done in the standalone version) generate lots and lots of errors. This topic is also discussed on the SMF forums: http://www.simplemachines.org/community/index.php?topic=27409.0

After uninstalling the bridge my forum error log still keeps filling up to such an extent that I have to deactivate the error logging completely to avoid filling up my server harddrive.

The log looks like this:

Thanks for the followup. I edited the error reporting feature instead so that it has stopped logging errors... The database got filled up too fast for me to handle!
