NinjaFirewall Stops Product Adding to Cart

If products are not being added to the cart, it may be caused by NinjaFirewall blocking certain requests required by Chamevo.

Solution 1: Disable Base64 Decode Option

1. Go to NinjaFirewall settings.
2. Disable the option: Decode Base64-encoded POST variable.
3. Save your changes and test adding a product to the cart.

Solution 2: Whitelist Action (Advanced Users)

• If you are experienced with development, you can whitelist the Chamevo action directly in the .htninja file.
• This allows NinjaFirewall to ignore requests from Chamevo while keeping the firewall active for other traffic.

Solution 3: NinjaFirewall Premium (For Non-Developers)

• If you are not comfortable editing files, you can upgrade to NinjaFirewall Premium.
• The Premium version allows you to whitelist specific functions via the plugin interface without touching code.
