# SSL problem

 * [6 years, 7 months ago](https://wordpress.org/support/topic/ssl-problem-18/)
 * We have been fiddling with the site to try to make it faster and we succeeded,
   partly with Autoptimize.
    But the calendar page stopped rendering correctly, 
   due to about 30 errors like this:
 * :1 Mixed Content: The page at ‘[https://xxx.org/calendar/&#8217](https://xxx.org/calendar/&#8217);
   was loaded over HTTPS, but requested an insecure font ‘[http://xx.org/wp-content/plugins/revslider/public/assets/fonts/revicons/revicons.ttf?5510888&#8217](http://xx.org/wp-content/plugins/revslider/public/assets/fonts/revicons/revicons.ttf?5510888&#8217);.
   This request has been blocked; the content must be served over HTTPS.
 * When I turned off CSS in Autoptimize, those errors went away and the page rendered
   fine again. But we took a hit in speed, of course.
 * Any solution to this? Why is the CSS asking for unsecure fonts?
 * THANKS!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fssl-problem-18%2F%3Foutput_format%3Dmd&locale=en_US)

 * hmm, the file `wp-content/uploads/hummingbird-assets/3daff643a8670a75e309e9d54cefe4a4.
   css` (which is the CSS-optimized version of the revolution slider plugin by Hummingbird)
   still shows the font URL’s as starting with `http://` so the problem is very 
   likely with Hummingbird. Moreover combining plugins to do CSS/ JS optimization
   _can_ cause conflicts, so maybe retry with CSS (and JS) optimization off in Hummingbird?
 * hope this helps,
    frank
