XF 1.1 Logging in Problems

When trying to login to my forum or AdminCP, it logs me out immediately or whenever I change the page unless I selected 'stay logged in'.

(Also, if I use the Account Switch feature [while 'stay logged in'], whenever I try and post, it logs me back to the original account.)

Prior to this, I was having issues accessing my site and my server, through the troubleshoot, asked me to clean the cache and to try 'ipconfig /flushdns', so I'm not sure if this is connected.
 
No, no errors. I put in my login details and it works, I get logged in. But when I change to a page or to a thread, I'm logged out. I only stay logged in if I select 'stay logged in'. If I try to enter the AdminCP, it keeps logging me out.
