We have an issue with an episerver 7.5 site. When clicking between sites in a multiple site solution we get the error sometimes!
Page could not be loaded (HTTP 400)
The page you were trying to access could not be loaded. This could be due to maintenance, please try again later or contact us if this problem continues.
Has anyone seen this problem before?
The missing # in the URL causes the problem.. Why I do not know at this time. But here is more and what is written in the log file down below.
2014-08-06 15:14:45,816  ERROR EPiServer.Global: 1.2.5 Unhandled exception in ASP.NET
System.Web.HttpException (0x80004005): A potentially dangerous Request.Path value was detected from the client (:).
at System.Web.HttpApplication.PipelineStepManager.ValidateHelper(HttpContext context)
I have googled a bit and not found anything about this except for standard info about potentially dangerous values. But this is episerver itself (seemingly) that is redirecting the editor to the incorrectly formed url)
