Wrong default-value for $size in get_the_post_thumbnail_url()

If you use get_the_post_thumbnail_url() without setting the $size value, it seems that get_the_post_thumbnail_url() doesn't work!

Look here:



So if you want to use get_the_post_thumbnail_url() correctly, you have to specify $size = 'thumbnail'. Otherwise it doesn't work, because the default is "post_thumbnail" and this is meh.

Hi @souri_wpaustria,

Thanks for the report. In this case, post-thumbnail is the intended default size since the function get_the_post_thumbnail_url() is meant to return the post-thumbnail size set when a theme declares post thumbnail support and uses set_post_thumbnail_size() to set the size for the post-thumbnail image.

At this point, the function has defaulted to the post-thumbnail size since it was introduced in 4.4, so changing the default value would result in backwards compatibility issues for any themes that are expecting the current default size.
