Thank you so much for looking. It was my first thought as well, however, this is one of the Admin accounts and should not be "flagged" for expiration. In addition, before the migration to the dedicated server, this functionality was working well for the same account.
One more thing that has been an issue since migration (which I've already solved):
Since this site is using the SSL certificate, I had to change the absolute path in the Site Settings in DW (from http://...... to https://) in order to connect to the Database... So, something tells me there is some other settings that should be updated for the site in order to fix this issue.
Please look at the PM
