I am getting a 403 Forbidden Error when trying to bring up Properties on a Tag or a Hyperlink.

The Insert Image and Insert File works just fine.

I'm on Version 6.7

I have a site that works just fine with it and 2 sites that don't.  They all share the same virtual directory.

Comparing the different sites, I don't see anything that pops out.  The one that works is just a regular ASP.NET, the new site uses Bootstrap.  It does use the FriendlyUrl's, but not sure if that has anything to do with the error.
