Hello/Hi/Greetings,

Just created Piwigo Gallery on Bluehost and used "drag and drop" option to upload some photos.
I couldn't understand why my sort selections were not working.  Then I noticed that the creation date is missing in the uploaded photos.  It is present in my original photos. I must be missing something but I can't locate an explanation. Please help.  Thank you.

Piwigo version: 2.7.4
PHP version: 5.4.40
MySQL version: 5.5.42-37.1-log
