metadata is not being updated

Hi there,

I changed the standard wordpress thumbnail size, deleted image versions of that size from the server and regenerated the thumbnails. Unfortunately, the metadata for the images was not changed which resulted in 404s on the websites because the metadata is now pointing to files of the old size which no longer exist.

Wordpress-Version: 4.9.8
Plugin-Version: 3.0.2

Any advice on how to fix that (regenerate the metadata)?

Thanks in advance!
