Forum Trouble with users logging in in forum

[محروم.كوم]

Hello
This is a problem that occurs once a month. Every member on the site including myself have problems loggin in. They can type in all their info and the page will pop up and say "thank you for logging in {username}" but the next page to pop up will "log them" back out. THey are still logged in the system but cant not view the forum unless they click on WHATS NEW or some other tab on the site.


Why does this happen. Its happens very often and right now its getting a little crazy with my new members not being able to log in. __DEFINE_LIKE_SHARE__
