Thanks for the screenshots and login, however, I can’t get to the
wp-admin page. It just redirects me to the home page.
I now understand the issue. Yes, when upgrading to ACF5, your field group ID’s will change. This is due to the old v4 data being left in the DB and new v5 data being created. This allows you to safely downgrade to v4 if necessary because all previous field data still exists.
You will need to update the ID’s where you have used them (acf_form)
As for the duplication issue, I am not sure what is causing this. Is it possible that you have 2 copies of ACF PRO (plugin and within theme)? Perhaps the migration is running twice? I am not sure as of yet
