  • Hello MSZ,

     

    You will need to allow characters that triggered in your violation if you want to accept them. To do that :

     

    1) Go to "Security ›› Application Security : Headers : Character Set"

     

    2) Change the State for characters that matched

     

    3) Apply your policy

     

    4) Test again

     

    Regards
