Just fixed it myself with a temporary work around.
In my case grunt wordpress deploy changes the serialised array values on pull_db and push_db, which is good. But in this case there are mulitdimensional serialised arrays used by this plug-in (post_meta -> rpg_all_photos_details) and the main character count is not updated in this run.
Follow me
- Make export from WP Export function -> Responsive Photo Gallery
- On new location delete all the galleries
- On new location do the import via WP Importer, asign all to correct user
- Run search replace with on the post meta table(rpg_all_photos_details), use https://github.com/interconnectit/search-replace-db
- Done all galleries are working again.
If you are moving the database by hand, just use the search replace db tool in the link above. It changes the multidimensional serialised arrays correctly. No need for the other steps.
Happy moving!
