Before they speak for me to try the solutions presented in the suggested document in the error message, I have tried all, the error not any of them * Messages that appear on the console are as below: * Error 1 Mixed Content: The page at ‘[https://www.emagrecerevivermelhor.com/wp-admin/customize.php?return=%2Fwp-customize.php?return=%2Fwp-admin%2Fplugins.php%3Fplugin_status%3Dall%](https://www.emagrecerevivermelhor.com/wp-admin/customize.php?return=%2Fwp-customize.php?return=%2Fwp-admin%2Fplugins.php%3Fplugin_status%3Dall%) 26paged% 3D1% 26s: 1 admin% 2Fplugins.php% 3Fplugin_status% 3Dall% 26paged% 3D1% 26s ‘was loaded over HTTPS, but requested an insecure stylesheet’ [http://fonts.googleapis.com/css?family=Lato](http://fonts.googleapis.com/css?family=Lato): 300,400,700,300italic, 400italic, 700italic | Roboto + Condensed: 400italic, 700italic, 400,700 ‘This request has been blocked; the content must be served over HTTPS. * In this error I tried to locate where the http to append the s but I could not, I opened the file customize in wp-admin via ftp but I did not find the line there. * Have one more error below: * Error – 2 inline-cloudflare-rocketloader-executed-14.js: 70 Uncaught TypeError: Can not read property ‘addEventListener’ of undefined at onload (inline-cloudflare- rocketloader-executed-14.js: 70) at window.onload (scripts.min.js: 14) at loadAsyncScript( inline-cloudflare-rocketloader-executed-14.js: 38) at eval (inline-cloudflare- rocketloader-executed-14.js: 19) * If you can help me, I’ll be very grateful.

The issue could be related to a caching plugin probably not well configured?! Do you have any caching plugin active? Did you try disabling them? * Thread Starter [marcosaguiar](https://wordpress.org/support/users/marcosaguiar/) * (@marcosaguiar) * [8 years, 6 months ago](https://wordpress.org/support/topic/customize-not-loading-error/#post-9716320) * Thanks for replay. I disabled all the plugins, except the hueman Addons, but the error continues, seem to be in loading the plugin. I had an old version of the theme where customization was not done with plugin, everything was working fine, when I updated, the colors became thema’s initial patterns, I lost almost all the customization I had, and without the plugin I could not redo the When I turned off all the plugins, the only thing that changed was that they returned the initial colors, but banners and sidebars, nothing came back, and as I said, it continues to give the error message, I can not access the customization. * Thread Starter [marcosaguiar](https://wordpress.org/support/users/marcosaguiar/) * (@marcosaguiar) * [8 years, 6 months ago](https://wordpress.org/support/topic/customize-not-loading-error/#post-9716418) * Hello When I was activating plugin one by one, I discovered the plugin that generated that error message 2 The Error2 (js error) instead …, is the “Async JS and CSS”, but still with I said the previous message continues giving the error, but when going to the console , error 2 does not appear any more, but appears in red 08 “mixed content http errors …”, I will copy all of them and post in next message * Thread Starter [marcosaguiar](https://wordpress.org/support/users/marcosaguiar/) * (@marcosaguiar) * [8 years, 6 months ago](https://wordpress.org/support/topic/customize-not-loading-error/#post-9716835) * Following are current errors in the console, all in red: * 1 – jquery.js?
