[SOLVED] Problem with logging in on forum.

For some odd reason, the Xonotic forums do not like me when I try to login. After logging in and getting redirected, I am taken to my ISP's search engine. I then must go back and refresh the page to use the forum. This only happens when logging in after trying to reply to a topic.

This is quite strange... Usually it should redirect you to the previous page.
What do you mean by "your ISP's search engine" ? What is your ISP?

my ISP is CenturyLink, formerly CenturyTel.

After logging in and getting redirected, I am taken to my ISP's search engine.

Arf, that is such a pain with ISP provided DNS. I always get bigpondsitehelp.com when I try a domain name that doesn't exist, it's sooo very helpful and makes a tonne of sense :p Worse still, it returns HTTP 200 (!)

Not entirely (or even remotely) sure, but it may be a DNS problem, so try using Google Public DNS to see if it is.

It seems Centurylink hijack 404's, and also bing searches! Definitely change your DNS server to something less abusive...
