I recently pushed a new theme to my site and noticed that I could no longer use JetPack’s Carousel feature. It was breaking due to a javascript error.
$.browser.mozilla |
I did a little research and it appears that the JetPack Carousel is not currently compatible with jQuery 1.9 which removed the browser detection code. If you’re running into this issue you can add it back in using the code here: https://github.com/pupunzi/jquery.mb.browser/archive/master.zip. This is only a work around until JetPack moves to the latest jQuery, but it might help with other WordPress plugins that depend on jQuery’s browser detection.
Here is the code in full incase that link is ever taken down.
