Users receive "Request has been denied due to unacceptable characters in the input" error trying to reach MarkView Home page


Question / Problem: 

When trying to reach MarkView Home, users who are using the Google Chrome or MS Edge browsers may receive the following error message:

Request has been denied due to unacceptable characters in the input

Answer / Solution: 

This error is caused by an update to the Google Chrome browser made by Google which puts previously unsupported, double-quote characters ("") in the Chrome's internal HTTP request headers that MarkView doesn't allow.

The same issue occurs in newer versions of MS Edge.

MarkView has an update which overcomes this browser situation. It is included in the MarkView fix pack, and the MarkView fix packs - both of which are available for download at It will also be included in the forthcoming MarkView fix pack.
