Description of problem:
Step 1: Click upload button.
Step 2: Click “Choose Files” and select an image from your PC. Make sure the image selected DOES NOT have any date in the “Date Taken” element in the image metadata.
Step 3: Click on the Date Picker to try and set the date.
By chance the photo I was trying to upload did not have a date set in the “Date Taken” element in the image metadata …this field was blank. The blank field caused the Date Picker to not work properly. It detected that there was an invalid date, but would not allow you to choose a date. I worked around this issue by setting the “Date Taken” using Windows Explorer utility.
This is probably an unlikely scenario as all cameras / devices will normally set a value in this field when the picture is taken, but on the off chnace that the users camera settings are incorrect (as mine were as I had my camera repaired and some of the settings were reset), then this issue will occur.
