I've run this since JomSocial 1.6. It works on 1.8, too, and they did release a fix for one issue in 5.0, but you may still run into difficulties. It seems like they might have a core group of people who test and have a direct line to the developers, but they generally don't even respond in the support forum. I resolved my own issue and posted that in the forum for the benefit of others. Not one word from Latitudweb about it. I'll give them the benefit of the doubt for now. There could be good reasons for it, so I renewed my subscription, but I hope their serious lack of a "support" forum presence changes. I'm not by any means the only person with this complaint.
