I am using twenty fourteen theme to make another theme most of the files are same including the functions.php file, but the problem I am having is , When I add image size ( with true crop, hard crop mode). The images are not getting cropped on the front-end, only getting resized, but I want them to get cropped also. I will appreciate any help.
If your images were uploaded before adding the new image size, you might need to purge the thumbnail cache. I found that Force Regenerate Thumbnails works really well to clear the image cache and regenerate images in the new sizes and crops/
