Community Builder bug

I install sef-ext.php (community builder), but now if i log-in in my site joomla return (access denied.. please login or register, I think that return a incorrect link (only if I up new .htaccess blank the login works  > ... )

All your CB links in usermenu must be with public access. Please search this forum, it has been discussed before.

all cb links in usermenu are sets to public access, I think there is a problem in file .htaccess boh

I have read all the discussion in the forum, (I try to put component (cb with public access to usermenu)), the remain! I try to disable sef advanced, ignore community builder component, change the sef (under cnfiguration to OFF), and in all of this cases i can't login (You are Not authorised to view this resource, please login or register ); only if i delete .htaccess login works!

Send me the access info on mail and I will take a look.

Please How was this problem resolved as I am having this on one of my sites.
