Yes, that is correct.
I disabled the sticky posts and tried the KALE theme again. And this time everything worked smoothly.
That was my observation, however, perhaps there was something else (that I am unaware of) that caused the fix.
I am a newbie… so I might get some things wrong.
Hope this helps.
GREAT THEME by the way. Would purchase, but the monthly (maintenance?) fee makes me uncomfortable.
Got it resolved by disabling/removing sticky posts.
I’m having the same issue as @nickyreyn. Tried your suggestions and nothing works. Could it be a plugin conflict? Is the slider working for others??
