Hey all! I have an issue with the Featured Image on post page. I've added the add_image_size function with exact width and height of the thumbnail. I understand that the thumbnail should be cropped exactly to the size i put inside this function. But the result is strange: the thumbnail is getting only the height right, but the width is anything but the size in the function. For example: in the function width 303, height 100, on the page i see width 133, height 100.
What causing this and how it can be fixed?
