Why is the plugin using the style.css of my theme at the Tinymce where you enter your content per slide?
The background of my site is gray, and my body text is also grey, so you don't see what you type...
In the head of the iframe is loaded (which is the standard Tinymce style): <link type="text/css" rel="stylesheet" href="mysiteurl/wp-includes/js/tinymce/themes/advanced/skins/wp_theme/content.css">
but also my own style.css (which don't need to be loaded, it's now loaded 2 times): <link type="text/css" rel="stylesheet" href="mysiteurl/wp-content/themes/my-primashop-wc/style.css">
mysiteurl is replaced with the real url of the site.
