Subs-Post.php errors SMF 1.0.5

[bridgetc]

I have installed the board and changed the theme with no problems.
However I am having errors with subs-post.php and I'm not sure what it is.
I'm not all that skilled with reading php code, so any help is greatly appreciated.


This same error has popped up many times, and most recently when trying to send a private message....

2: fsockopen(): php_network_getaddresses: getaddrinfo failed: Name or service not known
File: /home/websites/**********forum/Sources/Subs-Post.php
Line: 556

I would post a link to the board, but I don't want to advertise it to the world.
I can send URL in private message.

I think I figured it out, I had smtp set up for messages and mail. I switched it to sendmail and I'm pretty sure it's all better.
But thanks!

If I have any furthur issues with it I'll be sure and post.

That means that you entered an invalid address for the mail server. If you want to use SMTP, verify that the mail server address is correct.
