    Recieving many of these in the past few days. Possibly tied into the random server errors my members are seeing when trying post/PM/post images (prevents them from doing so):

    Code:

    Try disabling your resources (if you have any) via config.php and see if the problem persists.

    How do I do that? I don't see an option in the main config.php file.

    See if this helps.

    Are you using SMTP?

    That just indicates that your SMTP connection info isn't right. Likely the username and password, though I would double check everything. If you're not sure, check with your SMTP provider.

    I am using SMTP, and I've doubled checked the info and it's correct. I haven't had this error until recently, and I've also been receiving emails properly (PM notifications). I just sent a test PM and got an instant email alert.

    If it's sporadic, that is likely indicative of an issue with the SMTP server itself. Not a lot you can do if you don't operate the SMTP server. (One of the reasons we generally recommend the standard PHP mail options over third-party SMTP servers.)
