I am currently developing a plugin that uses shortcodes. On my localhost everything works fine just using the shortcode, for example:
[bbit bandname="Lady Gaga"]
This shows a list of bandsintown.com gigs for the artist, like it's supposed to. Now when I install the plugin on a live website from the WordPress repo and I use the exact same code, the post on the website shows the shortcode, instead of the list of gigs.
- I already tried other plugins using shortcodes (like Contact Form 7) and they just work.
- The localhost WordPress and the live environment use the same theme (a custom child theme for "Responsive".
- Last version has been pushed to the repo, I checked.
- When I install the plugin on the localhost (from the repo) it works as well.
What can be the problem here?
 I downloaded the Debug Bar and the Debug Bar Shortcodes. It revealed that there's something wrong with registering the shortcode.
