Hi everyone I've been used JFBConnect in joomla ver 1.5 and jfbclogin module but I am migrating in joomla version 3 the jfbclogin module are not working. Any idea will appreciated and if there an alternative to this jfbclogin module. Thanks
Hard to tell.
It's most likely still using old deprecated and removed code that Joomla 3.x doesn't support. The only thing you can do is check the developer site to see if there is a Joomla 3.x compatible version of the modue, else find an alternative extension with similar features.
According to the developer site, the later versions support Joomla 2.5 and 3.x, however I'm aware this is a commercial extension therefore you may not wish to purchase it. Perhaps someone else who has used a similar extension could provide an alternative if need be.
