It's weird. I've tried several scenarios similar to yours using different browsers, but couldn't reproduce your error. You talk about "list page". List page is Timeline My Posts or Unanswered or Latest Posts. right? It shouldn't be problem with your operating system, it's more related to your browser.
Which browser do you use? Actually, the site has been optimized for bunch of browsers including IE8-11 (Internet Explorer), Chrome, Firefox, Safari, Safari Mobile, Android browser, Chrome mobile, Opera, Opera Mini, etc.
If you repeat the same issue with other browsers then we have to look at your account particularly, perhaps one of posts showing in lists is corrupt some how and prevents page to load correctly.
Hi guys,
Our dev team deployed possible "session timeout" issue fix. We are still not sure if this works since it needs some time to lapse before we can check the status. Let me know if you still experiece this sudden log out issue.
Thanks!
