Recently I discovered that our version history isn't working anymore. In our SharePoint 2007 I can see the file history but when I try to open the file I get an error message that says " Could not open 'url/filename' ". I can create
new versions but still can't open any of the previous histories. I've also tried to open a previous version from the open file (like in MS Word > File > Versions > Manage Versions) but I get the same error. Any suggestions?
Check the ULS logs when you attempt to open the version to see if there is an exception. With SharePoint 2007 I find using running
ULS Viewer on the server in auto mode works cause I can pause it right after clicking and scroll up for the exceptions.
