WordPress returns old thumbnail size after changing media settings

I have had a requirement to update a WP build so that the thumbnail size changes from (the default) 150×150 to 500×500.

add_image_size wont work after get_intermediate_image_sizes

I am using the function get_intermediate_image_sizes() to check if an image size already exists, and if not create it.

You’d say that isn’t a problem because the original is the resolution I need, but I get the image later on with: wp_get_attachment_image_src( $meta[‘background’][0], array(300,300) ); And if […]
