Hello 🙂

 

So if I understand correctly, you are trying to visit a URL with a '%' character in it and it is causing issues?

 

If you want to escape the '%' character you should use the following: '%25'. SO for example:

'www.example.com?percentage=25%'

becomes:

"www.example.com%3Fpercentage%3D25%25"

 

You can test this easily by opening your browser console (right here on this page if you want) by hitting F12 and then using the following native function: encodeURIComponent():

    It looks that your URL is incorrect: "Bad escape sequence: %3Q" means that there is a sequence "%3Q" which is considered as an URL escaped sequence, but it's not valid.

     

    Can you post the complete URL (at least the part after the pagename)? How is this URL created?
