Each time I post (I know, a whopping 3 now I think!), I get this at the top of my page. Odd thing is I'm not trying to send an e-mail, and my posts are being added as they should be.
I was seeing that on occasion too. I think it's an error in the forum software trying to send out the email alerts which go out to people following the posts to indicate there's been an update to the thread/post.
I get it most times I post. I'm sure it won't be happening forever. Doesn't seem to make any difference to any aspect of BLF life. I could be wrong, but I thought I read sb's explanation of it somewhere..
Server that our forum is running on cannot send mails, and frugal is smart enough to detect that and display a warning.
This error sometimes comes and goes.
Other than people not getting mail notifications, there shouldn't be any other consequences. For regular users that are reading and posting no action required. Other than maybe notify our admin.
