Hi James,
Apologies for the late response.
Could you run the following test with your browser’s developer tools?
- In your browser, open your Developer Tools (instructions on how to do this for each major browser can be found here)
- Open the ‘Console’ tab if it is not already open
- Reload the page and attempt to create key
Do you see any errors appear in the developer console? Could you send me a copy of screenshot of those errors?
Alternatively, if direct site to site migration fails to work, the quickest way around is to use one of the alternative transfer methods to send your backups to your new site. These can be found in Step 3 of the migration guide: https://updraftplus.com/faqs/how-do-i-migrate-to-a-new-site-location/
I recommend using the same remote storage location. eg. Dropbox
Best Wishes,
Bryle
