Hello,
I'm using JA Megafilter component for K2. The K2 plugin is properly installed and enabled.
No items are loading and in console I get the following error:
main.js:259 Uncaught TypeError: Cannot convert undefined or null to object
at Function.keys (<anonymous>)
at Object.success (main.js:259)
at c (jquery.min.js?5c86a5e861ca271fc1f476cf5b3c43a0:2)

at XMLHttpRequest.n (jquery.min.js?5c86a5e861ca271fc1f476cf5b3c43a0:2)
I use K2 v2.9 and Joomla v3.9.
Thank you,
Yannis
