Plugin Firewall Test Mode is obsolete and is pending deletion from BPS Pro. If the cURL scanners are unable to find plugin scripts to whitelist due to something on your website preventing the cURL scanner from finding those plugin scripts then the Plugin Firewall Test Mode tool will also NOT be able to find those plugins scripts. A much better way to check your site is shown in the video tutorial link below. You can check your site at any time using a Proxy and would not have to wait until tomorrow to check your site with a Proxy.

Manually adding plugin scripts to the Plugin Firewall

Checking Your Security Log For Plugin Scripts To Manually Add To The Whitelist
If a plugin script is being blocked by the Plugin Firewall then a Security Log entry will be made and you can manually copy the plugin script path found in your Security Log to the Plugins Script/File Whitelist Text Area. An Example of a Security Log entry for a plugin script that needs to be manually Whitelisted is shown below. You would copy this plugin script path - /bbpress/bbp-theme-compat/js/topic.js – to the Plugins Script/File Whitelist Text Area, click the Save Whitelist Data button, click the Create Firewall Master File button, select the Plugin Firewall BulletProof Mode Radio button and click the Activate button.
