Security Settings? Error code 2C171/1

[RextonXVT]

Hello,

Recently we upgraded our forum to 4.1.7.

After I executed some the recommended security settings in the security centre members are not allowed to open content that is linked in a post. See attached screen shots.

Please can some one advise me how to solve this issue?

Thank you,

Walter
