@mercime
that is not the answer I expected. and your answer does not help me.
I certainly use the latest version of wpmu, and running normally. Only that plugin are problematic. I also do not make code changes of buddypress or wpmu.
Facebook Connect is not working with BuddyPress trunk version so I had to delete it, but it worked in BP 1.1.3 set up in subdomain structure. Some couldn’t get it going on subdomain install but went well with subdirectory install of WPMU. Those are only some variables which might affect the install of the FB connect plugin..
“Connect URL in the application settings editor”
– somewhere in Facebook Config Page, 2nd step or so, make sure you have something like this:
Connect URL: http://yourbuddypress.com
Base domain: yourbuddypress.com
Maybe someone has gotten it to work with trunk already. Good luck.
The standard support questions which mercime linked to help us help you. Despite the fact that FB Connect is not BuddyPress and as such is a third-party plugin, there are plenty of existing threads in these forums about issues with FB Connect
