I am trying to keep a URL (/plesk-stat) from being processed by DNN, and have set the path in the database field:

AUM_DoNotRewriteRegEx 

/DesktopModules/|/Providers|/LinkClick\.aspx|/plesk-stat

However, when I go to that URL, I get an error that indicates the Rewriter is requesting the permissions for that directory. Am I not successfully excluding /plesk-stat from the rewriter? Here is the error (DNN 7.4.1).
