Image "File Type Isn't Allowed"
This has been happening for some time now. Originally I thought it was just a glitch and would clear itself up. It hasn't.
- Detailed steps to reproduce the bug (exactly how and when did it happen)
This has happened in multiple content types (Drag and Drop Image, Course Presentation, Image Hotspots, among others). It has happened on my Wordpress site as well as attempting to make at h5p.test.schulcloud-thueringen.de.
