Hi there @kalevigit,
There are a few issues here that are leading to your 404.
- You have no version number in the URL, which is required for all library assets on cdnjs.
- We don’t have a img directory under the most recent version of webui-popover, so even with a version number, that file will result in a 404. (See https://github.com/cdnjs/cdnjs/tree/master/ajax/libs/webui-popover/2.1.15)
Hope that helps, let me know if you need anything more.
