Hello,
I could send you the schema in SQL, but it is safer if you do the following:
1. Delete the wp_wallets_revision option from the DB:
DELETE FROM wp_options WHERE option_name = 'wallets_db_revision';
Make sure to replace wp_ with whatever prefix your DB is using.
2. After deleting the option, deactivate the plugin and reactivate it.
I will make a note to make the uninstall script delete the DB revision so that in the future a simple deactivate/reactivate cycle will repair the schema without manual intervention. This will be rolled out in the next release.
Let me know how it goes.
regards,
Alex
