We have two front end web servers and one internal. All 3 use the same file share. The upgrade went through no errors, but the 2 front end servers kept picking up legacy website default.aspx pages at random from the file share directory sub folders. Every once in a while it would display correct DNN home page but then bounce to another sub folder default.aspx page, I assume as the were cached. Any ideas on what may be causing the issue? The 6.1.5 version of the site was working fine before the upgrade and we have reverted back to it.
Example: www.site.com/ would display www.site.com/animalcare once that legacy subfolder page had been visited or www.site.com/swmd would display or any other random default.aspx in a subfolder in the file share.
