Hey Ben Ritner,
I deleted the basic slider by choosing “non” and saved. The error message (and the slider) were gone.
Afterwards, I put all pictures via upload in again, also selected also the “images in carousel”-option: the error was there again.
Then I tried to select “equal ratio images” – no error… also with the other options…
Only with the carousel slider, it appears… (this ist the selection, my customer wants to have – and it was ok for about a year… what did change?)
