An update; after some research i found out that it seems the bug is in the checkboxes. When I add a checkbox, no matter where I do it on the side, it will only show up the label text, but not the checkbox itself. Left of the text, I see a very small box, perhaps 4x4 pixels. When i try to change the height of the checkbox, it’s locked. The only thing I can do is change the lenght of the element (which includes the length of the text value).
When I change the lenght, the height changes with it, so these 2 are connected. When I set the length to 10, the height becomes one. The max is a length of 25, which makes the height become 4. But 4 is also the max height, it’s not possible to make it longer.
So, very strange behaviour. Anyone who has an idea what’s going wrong here? And remember; this also happens if I delete all the cache, it also happens in a complete new site when I create it. It’s a really weird bug… please help!
