Pop-up works but it displays nothing but "There was an issue displaying this preview".
Topic on Extension talk:Popups
Please provide more context, or direct links to specific examples, so that people can understand where the issue is (which wiki, which page, etc) and try to replicate it, or provide other relevant advice or pointers. Thanks.
Sorry...
I think it's solved now though. The page cannot start with ==TEXT== and images are not drawn from the gallery code. So for those that might have the same problem, your page should start with just some text, maybe a short description depending on what you're making, before starting to put in headings. And there have to be at least one image that is not inside a gallery tag.
