Sudden errors in my blog

Okay, I haven’t updated my website for some time, and when I went to check something, all of a sudden I’m getting errors instead of seeing my blog! I haven’t changed anything, I haven’t touched the site for a couple of months, and it was working fine then, so I don’t have a clue what’s going on.

This is the error that I’m getting:
Warning: main(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /home/lydia/public_html/index2.php on line 10

Warning: main(http://pink-moonlight.com/blog/test.php): failed to open stream: Permission denied in /home/lydia/public_html/index2.php on line 10

(my website is http://pink-moonlight.com)

i appologize if this is something simple and/or dumb, but I can’t figure out what’s wrong.
