I was on the site today 6/28/18 and suddenly found myself logged out. I did not leave the site. I did not exit my browser. I was reading threads and suddenly I was no longer logged in. When I log in now and check to login for keeps, forever, whatever the wording is, I get logged in but as soon as I exit my browser and then come back, I am not logged in again. I previously never had to log in again unless I cleared cache and website data. I have changed nothing, no software upgrades, no settings changes. Running Linux Mint 18.3, Firefox 60.0.2. I have made sure that I am not private browsing or pocket browsing. I have made sure that accepting cookies is enabled and I have even expressly allowed cookies from advrider.com. Any ideas what's happening?
