What is being blocked is the round bracket code characters/parentheses in the Query String: (Silver).
Do these steps to allow round bracket code characters/parentheses in Query Strings.
1. Copy this modified code below to this BPS Root Custom Code text box: CUSTOM CODE BPSQSE BPS QUERY STRING EXPLOITS
Note: If htaccess code already exists in this Custom Code text then overwrite it.
2. Click the Save Root Custom Code button.
3. Go to the Setup Wizard page and run the Setup Wizard.
