I have just set up the tikiwiki on my site, and am receiving this error when trying to register a "test" account (so I can see what normal users see):
The registration mail can't be sent. Contact the administrator
Now I'm fairly new to this, but other than the sender email section (which I've tried several different email addresses for) I'm not sure where else to look to troubleshoot that error. And it's a little cryptic for a novice like me to try and troubleshoot (there's so many new features here... I'm not sure where I'd start).
Any idea where else I'd go to troubleshoot this issue?
