Dolphin saves the backup files by setting the end COLLATE = utf8_unicode_ci
This is when you reload the backup set and creates an error and the module of payment and membership of dolphin that are no longer able to uninstall after a backup, removing COLLATE = utf8_unicode_ci to the backup file and restoring it works very well ...
I do not know if I was clear so you can watch the video you see what I'm saying.
