Same issue here. If a user posts a comment, WP will email me notification so I know the email works, but new users aren’t getting their emailed p/w.
Okay… I am a little slow. I got the permissions on the folder right, but didn’t set the permissions on the file IN the folder.
Sorry!!
I did a search on the error, and have seen other people with the same problem, but not any solutions.
Unfortuantly, no. I tried that fix and it had no affect at all. Any other clues?
