When trying to login to DotNetNuke, you may recieve the following error:
DotNetNuke.Services.Exceptions.PageLoadException: Input string was not in a correct format
and further down you may see something about the User TimeZone:
DotNetNuke.Entities.Users.UserProfile.get_TimeZone
To correct it. Check the value in the TimeZoneOffset field of the portal in the Portals table.
If it is blank, then set it to an interger value from one of the Keys in the table below.
If that doesn't work, you can also check the UserProfile table and make sure any record with a PropertyDefinitionId=37 has an integer value from one of the Keys in the table below.
