Hi,

could you please upgrade your joomla to 3.6.2?
this issue related with joomla code, jomsocial 4.2.5 has been compatible for joomla 3.6.2

if you dont want to upgrade it. I need to access site FTP, please provide me the detail

Regards

Yep, on this week I will do.

After an upgrade (Joomla and Jomsocial) the problem resolved, thanks!
