Hello,
I am running the latest Joomla and K2 and have run into a JSON error on the back end in K2, but only when I try to access artciles from a certain category. Other article I can get into, but the articles that are in my Video category, that have links to youtube videos using AllVideos plugin, I get the JSON error attached. Yet on the front end, when logged in, I can access the article to edit.
Any thoughts???
