I am having the same error. Have tried Safari and Chrome. Regular browser windows and private/incognito window. I have contacted QB Payroll Support 2x - I was told known issue but no estimated time to resolution, no follow up feedback on status. If I try to edit Export Preferences I get a blank window. I am trying to Export to QBO and not successful for the past 3 payrolls. Has any one heard of a solution or work around or another product that would successfully export payroll transactions to QBO?
