I can create galleries and upload images, but when it comes to bringing the two together, nothing happens. I select the required gallery checkbox the image edit form and click Save but every image I've uploaded is still linked to zero galleries.
In MySQL, there is the correct data in the below tables:
but no data exists in: wp_gallery_galleriesslides
I can manually enter data into wp_gallery_galleriesslides and then things work, but obviously this is not a viable option.
