I set up 10 subdomains with public registration, requiring email validation. They were all working fine, but yesterday they stopped working. I get error messages after the registration page indicatiing that I have trailing white space somewhere.

So, I turned off the email validation, but checked the send me an email when someone registers box. Still get errors after the registration page.

I haven't done anything else to the site that would cause email validation to stop working. Has anyone else been experiencing this?

I'm also not receiving emails from the concrete5 site when someone replys to my forum posts.
