When uploading a document on Access Education People, either directly to an employee's profile or in the Content menu, you will receive the error 'Server Error in Application A potentially dangerous Request.Path value was detected' if the document's title contains a symbol or character that isn't allowed.
To resolve this, you will need to amend the title of the document and remove the symbol, which will be displayed in brackets in the error message.
Go to Setup and click Content.
Click Documents, then browse until you find the document in question.
Click Edit.
Edit the Description field to remove the character or symbol.
Click Save.
