Adding security headers breaks Rumor theme

Hi there,

I tried to implement some security headers to my site and it seemed to have broken the theme. The CSS seems to be garbled up now with an all white background. I am using the Rumor theme. Any ideas? Much appreciated.

These are the securty headers used:

context / {

extraHeaders <<<END_extraHeaders

Strict-Transport-Security: max-age=31536000; includeSubDomains
Content-Security-Policy: default-src https:
X-Content-Type-Options “nosniff” always
X-Frame-Options: SAMEORIGIN
Referrer-Policy: no-referrer-when-downgrade
Permissions-Policy: geolocation=(self “”),

END_extraHeaders
}

Nevermind folks I figured the issue. It was caching….
