My sign-in keeps dropping off
 

For the last couple days the sign-in keeping dropping off; sometimes even going from one thread to another or when I try to post. I get a message that I am not allowed to post until I sign-in even though I was signed in before I wrote post. Anyone else having this trouble? Most irritating!

please also post what kind of device and operating system you are using

I have to sign in every time I go on this site. Never had to do that before.

I have to sign in whenever I'm using my cell phone but never on my home computer.
