Seems to be working for me on Firefox for Mac. Is a button not working for you or something else?
It's also working for me in Firefox 13.0.1 they may need to update their Adobe flash player. It works for me in Windows 7, windows XP and Linux mint.
Or it possibly could be a glitch with a stylesheet if you have applied one here recently..
have a great day hopefully you get it all worked out :-)
Thanks Eric and George. It's started working now. I have set my network as profile photo mandatory and just wondering a couple of members have already joined without their profile photos. Finally I could figure out the problem. The problem was with FF. Now is ok.
