Hello,
I am sorry to see that you are experiencing issues after updating the plugin.
Let me clarify the design changes on the course page. Based on the majority of client requests, we have significantly improved the course player and course page functionality. As you know, we have released a dark mode for the course player, and this feature will soon be available on the course description page as well.
Currently, theme users have access to only three course page designs, but more designs will be released gradually. Other free designs are nearly ready, and you will have access to them soon. Additionally, you will soon be able to control all elements on the course page as separate blocks, allowing you to change buttons, their placement, and make other adjustments as you wish. For example, even the enroll button will be controlled as a separate widget, enabling you to make any changes easily in the course page layout.
Furthermore, there will be an option to add a video to the course thumbnail, so instead of just an image, you can attach a video for the course thumbnail. Please understand that all these improvements required significant changes to the course page code to enhance performance and achieve these advancements.
Please follow the updates (and always make backups) to get the latest improvements and fixes.
Regarding the iframe issue, if you try to add HTML code or iframe tags to the description content using “edit with course builder,” the code will be removed upon saving due to security measures in the course builder. The builder is designed to eliminate input HTML elements for safety reasons. I recommend using the WordPress post editor to add iframes to the description instead. I tested this method, and the form displayed correctly on the course page. However, if you later make changes to the content and save using the course builder’s save button, the input codes will be removed again.
For the best results, I suggest creating a separate course for the video content test in description field.
Best wishes,
Lisa
