We have deployed an identical build with identical deployment methods to three virtual machines, two of which run as expected - the other does not.
The working boxes are running Windows Server 2019 with IIS 10, and Windows Server 2012 R2 with IIS 8.5. The bugged box is running Windows Server 2012 R2 with IIS 8.5.
This issue is that we expect dates to be displayed as dd/mm/yyyy but we are seeing mm/dd/yyyy, and currencies are expected to be prefixed with '£' but are prefixed with '$'.
We do have a custom configuration implementation running though there are no discrepancies between the settings.
The issue is almost definitely environmental due to the reproduction difficulties on different boxes but the previous version did not display this issue.
