Thanks for the tip. Made all the changes, made a post, but still not sending to anyone but the admin email.
Update: I changed it to send out an email with every new post. Now I get it to the admin email (which is also in the subscriber list), but not the other email I used. Any idea why it goes out to that one but not the others?
Resolved. I had deleted a category and the one post in there got slipped somewhere else and that somehow caused the problem.
Tried re-uploading the “subscribe2” sub-directory, but it’s still not showing up. Permissions are all correct as well. I have no idea what’s wrong.
