Forum not updating unless manually refreshing?

[shibby2]

Hey guys, A few of my forums (all on the same hosting account) are not updating unless you manually refresh the page. And even then, if you come back to the forum after a few hours, it won't even reflect the time you were there hours earlier...it will be from even earlier.

For example, you could first visit the forum at 9am, shut down your browser for 2 hours and then go back to the forum, and it will still say 9am. If you refresh, it will say the proper time (which would now be 11am).

If you leave again for 5 hours, and come back, it will say 9am again.

Any ideas? My members are going nuts. lol

Thanks!

Does your hosting have some kind of harsh caching module enabled?

I have no idea. I've been going back and forth with them all day, and they're no help at all. They just keep telling me that they don't help with custom coding (vbulletin), that they can only help if its a server-related problem. This just started happening yesterday, and I havent done anything to any of my forums in weeks. They keep saying they havent made any changes to the servers.

This really sucks, it's obviously a problem on the host's end, but they won't help at all. :(

Well, I clicked 'yes' under "Add No-Cache HTTP Headers" in the options, and so far it seems to have worked for now.

Any idea why I would have to do that all of a sudden? Is there a downside to having this on?

shibby2, I posted this a bit earlier on the VB support forum:

I have scoured the internet and have found bits and pieces relating to similar (if not the same issue) going back years.

Version 3.8.8

The issue: a few days ago (and never before that), my forum started requiring a refresh in order for new threads, new posts to show up, new posts results in "Sorry - no matches. Please try some different terms." even after I added two test posts. People have been experiencing login issues where they appear to be logged in then not, etc.

This is happening at all levels: forumhome and down.

I also experienced this: "Your submission could not be processed because the token has expired. Please push the back button and reload the previous window."

Nothing has been disturbed or touched setting-wise at my end.

Any thoughts? I have read all kinds of threads on this in various places but they all end without any conclusive help.

This forum has been running trouble free since 2003.

Thanks for any assistance you might offer.
