Hi,

I have migrated some blog data using sitefinty native api. now I am seeing a error on my system 

A potentially dangerous Request.Path value was detected from the client (&).

 

Full screenshot is attached below . I have tried solution provided over net using 

 

www.sitefinity.com/.../mvc-url-with-query-string-fails-if-the-query-string-ends-in-a-period

<httpRuntime relaxedUrlToFileSystemMapping="true" />

like adding httpRuntime exceptions for characters. But nothing worked in my case. rather I am getting 500 error when I add these to my web.config file. 

Please provide me a solution if I can fix them without changing records. 

Server Error in '/' Application.

Hi Chandresh,

Usually this exception is thrown when the URL indeed contains a dangerous character like a "*", "&". The error just shows that an url encode is not called somewhere where it should be. In this case the invalid character on your side is (&).

If you have created the blog posts using the API, please note to construct properly the url and replace the special characters in it.

You can check the below article for more details about the creating blog posts where you can see a sample on how to construct the url:
