I use a date field to save members birthdate, and discovered that with each update of the profile the value of the date field is decremented with one day. Same problem for two installations, and when I tested it here on easy-profile.com the same thing appears.
For my sites: Joomla 3.2 and EasyProfile 1.6
Any clue?
I discovered that by setting the HIDE ON EDIT PROFILE(frontend) parameter to YES, the effect was that the field was not updated. So I have a workaround, but this shouldn't be like described?
