Yeah! The problem with "Send PM when reporting?" option is fixed! Thanks!
Now, I'm getting error only with the third option ("Send email when reporting?"). Some of my recent games, I recieved an email notifying them, but I don't receive those emails anymore. When I put my email and try to save again this option, I get this message: "Please enter a valid email address". I tried two different emails but I got that same error message.
Here a print of the error message:
