Hello,
Mid thumbnails are not cached correctly. Specifically, only png files are cached. Jpg files are not cached in mid thumbnail. So my mid thumbnail med_cache folder only has png files.
On the contrary, my small thumbnails cache correctly, both jpg and png files. So the cache directory is full of both png and jpg files.
There is no problem displaying all thumbnails, mid and small. Only caching of mid jpg thumbnails is the problem.
Anyone has any fix for this?
