Something odd here

Site access from phone seems ok, yet PC is acting strange. Have tried a complete shutdown and restart
Site displays as if Im not logged in (gives me the option to Log in, or Join Free). If I click the Log in button, I get a quick activity bar, but nothing else.
When I go to the-website help & FAQ-or to -Questions and Suggestions-, it tells me I need to log in or register
YET
if I click “log in or register” button, it replies with “you are already logged in”

I can’t respond to any for sale ads either.

It might be some kind of restrictions put in place at work, I don’t know, but weird that it says Im logged in. (Unless it is reacting to my phone being logged in simultaneously.
I am going to leave out via my phone and see if that changes anything.
If anything changes, I will edit here or reply.

Edit: I was logged in via 2 different phones, and a couple instances on one of those. I logged out of all phone instances, yet PC still acts the same.
Any suggestions?
