I upgraded from 4.14 to 4.2. With this upgrade the Minima skin is used. The FlAGallery settings in the widget options are overwritten by the the skin. In my case instead of using the 150*150 px Thumbnails defined in the widget options other thumbnails (?) in the original picture scaling are used.
see attachments what the result looks like.
how can i get my original thumbnail definition transferred on the Minima skin?
