HTTP Headers - Content Security Policy - Tweaks

We need someone to tweak some settings (headers info) on a few sites so that security flags stop showing on Bitsight. It's mainly the Content Security Policy.

Please only apply if you know exactly what you're doing with headers.

The sites are in Wordpress and the administration of the headers will be done via a plugin called "HTTP Headers".

Any questions, please ask! I have the exact issues that need to be resolved, which I can send over to you.
