I installed this plugin for setting image sizes:
https://wordpress.org/plugins/simple-image-sizes/
After I installed this plugin, image sizes in BB stopped working. On photos, post slider and any module there is either only the option for full size or you can still select a size but it will always insert a full size image.
I deleted the simple-image-sizes plugin but the problem has persisted. No image sizes are available in BB.
I am using the example child theme with just the footer altered.
