I'm using Magento 1.9.3.4 AND KeyCDN. I configured the js/media/css files to come from CDN. On the CDN I enabled the CORS. The CDN uses HTTP/2, shared SSL and the Origin Shield setting is set to "disabled".
The problem is with my Magento WYSIWYG editor, because the javascript files come from CDN and I receive the error:
SecurityError: Permission denied to access property "tinymce" on cross-origin object
I tried to deactivate HTTPS for the backend but it's still enabled.
Please tell me if I can make some changes in order to make the tinyMce to work from CDN. Otherwise I'll have to change the JS path to use the server path instead of the CDN.
I changed System/Configuration/Web/Secure and Unsecure Javascript Base URL to: https://examplecdn.com/js/ instead of: {{unsecure_base_url}}js/
If you have any idea please say it. Thanks.
