I installed a SSL on a site. All the images that were uploaded prior to this still use http instead of https. I was looking to write some code to loop through the postmeta table and change the existing images. However, even if I go directly into the database and add the 's' after the http in the json object, it all breaks.
What is the best way of doing this in mass?
Velvet Blues Updating URLs seemed to work well for all other media on the site that was not uploaded and manage by Metabox.
Thanks
