This has happened 3 or 4 times today and once or twice in the past few days. On my Mac, I am logged out every time I re-access the site. No issues with any other websites. No recent changes to my Mac to create this issue, I don't think.
Looks like you are using Chrome on a Mac. If so, make sure you are not in Incognito Mode. Also, make sure you are not blocking cookies. Best was is to go to this address in Chrome...
chrome://settings/content/cookies
...and under Allow, click Add, and type in texags.com, and click Add
Thanks for the quick reply. That didn't fix the issue, though. Immediately closed the tab and went back in, was still logged in. Closed the tab for an hour, came back and was no longer logged in.
