I'm attempting to update several different courses simultaneously to set their end dates to the end of the year. I've been using course upload to use CSV files to make these changes, but whenever it changes the date, it also breaks the entire unit, causing it to display an error ("Coding error detected, it must be fixed by a programmer: Invalid string component. Please check your string definition").
What's a good method for changing course dates, or can you provide me with an explanation for how to make my current method work? Thank you.
I'm using Snap theme, btw.
