Final update:
Replace the URLs in the base64 decoded string, update the s:** values before the URLs with the new length of the URL, re-encode as base64 and it should start working again 🙂
After taking a further look, if you look in the database in wp_posts for an item with post_Type = ‘ris_gallery’, or just look for the shortcode for your slider.
Using the post id/shortcode id, look in wp_postmeta for that post_id and the meta_key = ‘ris_all_photos_details` there is a base64 encoded string which contains the URLs.
I haven’t worked out how to replace these URLs yet as doing so causes an error when trying to load.
I’m having the same issue. I’m currently using an older version of the plugin, though. Any advice would be appreciated. I can’t find the old domain anywhere in either the database or the filesystem, but the images are still loading from there.
