I have just posted a new entry to my blog; it has "double quotes" in the title...

The article views fine on the Home page, but when I click on the comments link at the bottom of the article I get an ASP Server Error with the following stack trace:

ArgumentException: Illegal characters in path.
System.Web.Configuration.MetabaseServerConfig.MapPathCaching(String siteID, VirtualPath path) +3609834
System.Web.Configuration.MetabaseServerConfig.System.Web.Configuration.IConfigMapPath2.MapPath(String siteID, VirtualPath vpath) +9
System.Web.Hosting.HostingEnvironment.MapPathActual(VirtualPath virtualPath, Boolean permitNull) +169
System.Web.CachedPathData.GetConfigPathData(String configPath) +382
System.Web.CachedPathData.GetVirtualPathData(VirtualPath virtualPath, Boolean permitPathsOutsideApp) +132

System.Web.HttpContext.GetConfigurationPathData() +26
System.Web.Configuration.HttpCapabilitiesBase.GetBrowserCapabilities(HttpRequest request) +133
System.Web.HttpRequest.get_Browser() +197
System.Web.ErrorFormatter.RequiresAdaptiveErrorReporting(HttpContext context) +104

All other articles are working fine, so I assume that it is the double quotes that are causing the exception; they are being passed to the URL as %22, and perhaps not translated back when trying to read form the XML file etc?? Just a guess.

Thanks for any assistance; my quick fix was to replace the double quotes with single quotes, which seems to work fine; but a proper fix at some point would be appreciated...

Many thanks,

Sorry for that. It has been fixed since the release of version 1.1. You can get the latest source code or wait a week for the 1.2 release. A quick fix is to add this line to the RemoveIlegalCharacters() method in BlogEngine.Core.Utils.cs

text = text.Replace("\"", string.Empty);
