Hello members,
As indicated by some of you there was in fact an issue related to the EXIF data parser on the Edit and Upload forms, which caused the entire page to crash.
Regarding the Edit button, the photo controls have been going through an overall in terms of layout. And as suggested by a member, the edit button is a crucial control that should not be buried in a menu. As such it is now located on the same level as the other controls.
An additional restriction is that this button should be presented only to the photo submitter and to members of the administration team. This restriction was not previously in place for the presentation of the button, it was only enforced on the edit form page.
Minutes ago was deployed a fix for the issues mentioned in this thread. They should not occur again.
Thank you all for your feedback.
Cheers
