Already used SMF
New clean Mambo (finally dumping Wordpress)
I installed the bridge on Mambo.
It shows this error at the top of the configuration page in Mambo for the bridge Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/****/public_html/magazine/administrator/components/com_smf/admin.smf.php on line 152
Sorry if this has been mentioned already
I assume that you are using two separate databases for smf and mambo?
Make sure that the db users each have full access to the other database.
Side note: I do not think that the current bridge with 2.0 works fully...
