"A newer version exists" problem every time I edit a topic

thycotic

I am not sure how to tell my version of DokuWiki but I think it is the latest stable release.

The problem is that whenever a user makes an edit to a page it gives the following error:

"
A newer version exists
A newer version of the document you edited exists. This happens when another user changed the document while you were editing it.

Examine the differences shown below thoroughly, then decide which version to keep. If you choose save, your version will be saved. Hit cancel to keep the current version.
"

It does this everytime and can't possibly be someone else editing everytime. Clicking Save ultimately seems to result in some sort of redirect war that ends in an HTTP header error (but does save the change). This problem never used to occur on our wiki but then started one day and we are not sure why? Is this a configuration setting gone wrong? (I don't want to report this as a bug in case we are just doing something silly). Any help appreciated. I love using DokuWiki and this is getting in the way.

Thanks!

?do=check is your friend.

Things never start without a reason. Did you change anything? Installed plugins? Upgraded/changed anything on the server? It sounds like the server's clock is running amok. Have you checked this? Maybe you disabled file modification dates for performance reasons? Start looking in that direction first.

Hi,

this sounds common to me, IIRC there was a bug introduced (and fixed right away) while changing the changelog mechanism of DokuWiki [1]. Do you run a daily snapshot? The problem was fixed somewhen at the end of Oktober 2006.

Any ideas?

I don't know of any changes to file modification times or the system clock.

I installed a fresh instance of DokuWiki next to the bad instance. It didn't display the same error - so it isn't some datetime stamp discrepancy. Then I copied over the data files and deleted the bad instance. I still have no idea what caused the problem - but apparently neither does anyone else! :)

Hope this helps you if you have the same problem.
