I am logged in Facebook.
But every 3-5 seconds a window pops up:
"Not Logged In
Please log in to continue."
If I click login, it will refresh the page. Then the message pops up again.
If I ignore it, it will also refresh the page. Then the message pops up again.
If I press ESC, the pop up window disappears, and then pops up again.
It happens on every page: news feed, setting, profile, message, etc., except the www.facebook.com/help so I can write this without being annoyed.
I've tried to change my password, change my email, activate login approval, disable the ad block, bypass the proxy, use another browsers, clear the cache and cookies, use another computer, but the results are the same, the windows still pops up.
I changed the setting by using m.facebook.com, there the message doesn't pop up. But when I reply a friend messages, after I press send, it goes to the m.facebook.com login page. I don't know if this is related.
My Facebook runs well on the Facebook android app and the messenger android app.
I don't think it is because my computer, or virus on it. Because my friend Facebook can log in and runs well on my computer.
Anybody here can help me solving this?
