When new user tries to log in via EasySocial, the following error occurs: Could not instantiate mail function.
Firstly I contacted my host. They said I need to choose php mail function. And there might be restrictions if "-f" option is used.
I thought this is like joomla/server problem, but then I tried to register new user via regular joomla login - and it was successful, no error and admin got email successfully. So maybe there is something that you can help with that?
