Hi,
sorry for the delay. busy times at the moment.
I created a slider from scratch without any images and I was able to publish it.
I also updated to the latest version 1.3.1.
It seems that it is not working when images (or svg graphics) are used from https://pre.wp-api.depicter.com.
Also when I click on “create slider” I get the following error message:
#RequestException:60
