Cookies/Log-In Issue

[محروم.كوم]

So yesterday, out of no where, my forum started having log-in issues where users would log-in and then be directed back to the home page, but not be logged in. But then when you navigate somewhere else it then shows you as logged in.

No changes were made to the forum. This just started happening. I haven't changed any of the cookie settings from the blanks in the default either.

Does anyone know where I can start troubleshooting?

Oh, and I cleared my cookies and that didn't do anything. I have already repaired the tables as well. __DEFINE_LIKE_SHARE__
