Hi Bruce,
Please disregard the license problems as this was on some non-public pages and somehow this is not occuring anymore :).
I have the latest version of UVG (2.4.3) installed and moved NeatUpload to the top of the HttpModules section. However, I have disabled it right now so that should be fine. I'd better uncheck the forcing of the lower case because I currently have this selected. A shame because I really love this option.
You mentioned the "ForceRebuild=False" settings, which can be changed in the Friendly Url Settings. Is this the setting called "Produce an Exception in the Site Log if two pages have the same name/path"?
Thanks in advance,
Marc
