Edit Menu does not work after installing Jomsocial 3.2
It seems that something is wrong with your joomla installation since it's also happening for non-jomsocial menu items, I suggest to ask about this on official Joomla's forum forum.joomla.org
As far I can see, this erorr does't referrs to any element of JomSocial, also you can try to uinstall JomSocial to check if it'll solve this issue, if not, then like I said I suggest to ask about it on official Joomla's forum.
