"The resume date must be after the start of the pause."

Where: Fees screen, Pause sheet, Planned resume date (optional) field.

Why: the pause starts today. A resume date of today or earlier is therefore refused: the resume date must fall after today.

What to do: choose a resume date after today, or leave the field empty for a pause with no end date. To cancel a pause that has just started, use Resume: on the same day, this simply cancels the pause.
