* I can get the JS/CSS optimized with this plugin but when I enable Optimize HTML
Code it breaks by SSL? And I get MIXED content warnings in Firebug for all my
images?
* What can I do? And thanks for the great plugin!!

* do you have the “CDN” field filled in in Autoptimize? can you try without that
one?

* Since we switched to HTTPS our CDN url is showing as our main URL – WPengine
must have masked it? Here is a path example to one of our images [https://dojmt.gov/wp-content/uploads/human-trafficking1-300×200.jpg](https://dojmt.gov/wp-content/uploads/human-trafficking1-300×200.jpg)
* So I used [https://dojmt.gov/](https://dojmt.gov/) as the Base URL but it didn’t
do anything and I tried it also without a Base URL and still breaks SSL.
* Anyway it could be a host issue – WPengine is assigning us a static IP and then
reforcing HTTPS hopefully that will help – I update this post as I progress –
thanks!!

* Thanks for the feedback.
* As Autoptimize does not change image URL’s (except for background images as defined
in CSS which can be rewritten to the CDN url configured in Autoptimize), this
presumably is not a problem with AO (but possibly indeed with WPEngine).
