Crop Thumbnail not working for Stackable Pages

Hello there,

we are using the plugin on our website for our bicycle citizen request. It works like a charm for the adjustment of our featured post images, but the testimonial site (created with the Stackable editor, https://wpstackable.com) does not seem to be recognized with it’s image sizes. When the viewport is narrow, the peoples heads get cut off and no cropping seems to help because the relevant image sizes are just not there. Maybe this issue is somehow related to this ticket https://github.com/gambitph/Stackable/issues/613 ?

Is there a way, to add the sizes needed for pages created by the stackable editor to the Crop Thumbnail backend?

If there is anything else you need to know I’ll be more than happy to provide additional information.

Thank you for your great work on this plugin, it already helped a lot.

Cheers,

Dennis
