I created a conditional formatting on a column with date ('Due date') and it worked fine until yesterday. This morning I noticed its not working anymore. I open SPD2010 and remove the condition and recreate it. In short I want the Font to change if due date is passed.
It works partially on SPD2010 (3 feb should also be in red. Today is 1 March)
However on Internet explorer only date from 2016 are formatted but non from 2017 even if the date has passed.
Any idea what can cause this?
