thank for this wonderful theme and your always great support.
i have recently a problem regarding the post thumbnail sizes: i set them in the customizer -> layout -> blog to a size 500px / 240px. now it seems, that it has no effect to the generated thumbnail. even if i change the sizes in the customizer (and regenerate the thumbnails) the thumbnails wont have the right proportions.
as you can also see, last year it worked perfectly. the new blog post seem to have this problem.
