RSS URLS for Validation

QUESTION – How can SSL Insecure Content Fixer plugin help with RSS validation?

ISSUE Feedvalidator.com and other RSS Feed validators expect http versus https on all feeds. WordPress is forcing https thus our RSS feeds are no longer valid. The feed validator also expects audio podcast urls in a page to be http versus https in order for the RSS feed to be validated.

Forum posts with solutions – but they cause other issues.

• https://wordpress.stackexchange.com/questions/217510/force-non-ssl-on-wordpress-rss-feeds-in-htaccess-using-cloudflare

Goals then:
• Have web page be secure SSL meaning all assets attached or called on the web page need SSL https
• Have RSS feed be valid using http for all feeds versus https (does that include all attachments – I believe so.

Even still…
Any solution would need to be workable for use of RSS feeds pulling for our Mobile app or Alexa apps so that it doesn’t cause issues there either.

How can your plugin help?
