How can I disable the mail handler?
All of them like New PM's..
I'm not 100% sure what handlers you're referring to. Why exactly do you want to disable them...??
Ok, Lets try to solve my problem.
I'm getting this error:
MyBB couldn't send the mail with PHP mail()...
Or something like that.
That's to do with the host, that's nothing you can change on your end. Have you asked them about it, or tried SMTP mail??
Ok. I'll see what I can do.
