For some reason Wordpress is ignoring my thumbnail sizes and keeping thumbnails cropped proportionately instead of specific dimensions. Here is what I have in my functions.php:
add_image_size('main-thumbnail', 728, 410, true);
and I have this in my content.php:
<div class="thumbnail"><a href="<?php the_permalink(); ?>"> <?php the_post_thumbnail('main-thumbnail'); ?></a></div>
I added these two things and regenerated my images with the Regenerate Thumbnails plugin, but it doesn't seem to matter. The images don't change.
For some reason Wordpress isn't recognizing the hard crop and is keeping the images proportional, so some of my images are way taller than 410 pixels. Why is this?
