I resolved some issues with the plugin with short code, and it worked like a charm. All of a sudden, no mail reaches me or the client, I tried to deactivate, uninstall, install the plugin again, deactivating plugins that I used after the functioning mail, but nothing works, still no mail! What shall I do? I have Autoconfirm set to YES. One thing I was doing in between was changing the login options to just be Wordpress, not Facebook, et.c in the .js file, I figured that could have done some damage, so I reversed what I had deleted, did not work, then I reinstalled the plugin once more, does not work.
