The forums and internal pages are timing out. There is a setting within vBulletin that allows for how long you can look at a forum of threads marked unread before it wipes out the unread listing. This forum has them set pretty short, comparatively. I view the forums by the new threads listing, and if it's 6 or 7 pages of posts, often I won't get through all of the new posts before the timer expires and the new posts are deactivated (bolded titles to not bolded titles).
Unless there are inherent issues with a vBulletin install (if you can read this post, there almost always are not), the issues are 99.9% with the user's browser. Here's my recommendation to fix your timed out cookies:
- Log out of the forum
- Head to your browser settings
- Clear all temporary files and browsing data, i.e. cookies, logins, downloads, cached pages, etc.
- Close the browser (not really necessary, but as long as we're starting clean...)
- Re-open the browser
- Log back into bikeforums.net and make sure you click "Remember Me" for next time
At this point, you shouldn't have any issues with the forum settings. This is a pretty simple cure for almost all forum issues. Sometimes new browsers don't play nice with the ol'
vB but more often than not, it's a user issue.
Hope this helps.
