The first time refreshing a page, after rebuilding the Visual Studio project, I get the following error. However, a second refresh works fine and so does the site from then on ... until the next time I build the project. I think it also happens if IIS is restarted.
Server Error in '/' Application.

I am also using Vorto, so have custom code for UrlProvider and ContentFinder. I have tried debugging but the error does not occur in my project code.
The line numbers in the stack trace are way off from the actual code. Interesting!
Empty entries are actually 'removed' from the list, so this is a long shot, but...
In your Web.config, are there any spaces after the comma in umbracoReservedUrls or umbracoReservedPaths?

Any ideas what might be causing this?
Hi Gordon,

umbracoReservedUrlsorumbracoReservedPaths?Well done Daniel ... spot on, full marks, top of the class!! :-)
The last entry in the umbracoReservedUrls list had a space after the preceding comma.
That certainly seems to have fixed it ... but I think it would be a nice fix if spaces could be handled.
I'l add an issue to GitHub for the next release :)
Hi Gordon,
This is fixed in 3.15!
