I just upgraded to 2.2 but i've had this issue since i first installed over a year ago. I've not been able to fix it yes. I hope someone has an answer for me.
When I first installed my blog it was in a subfolder (eg: http://www.xyz.com/blog) My email notifications and everything worked fine.
I then moved it to http://blog.xyz.com and ever since no email notification is working at all. i cant figure it out. I don't get emails when new comments are posted. New users that sign up don't get their passwords nothing.
This is a big problem because i have a bunch of users that sign up, and i have to keep monitoring daily and manually changing their passwords and emailing it to them.
Can anyone please help
