I am using for 2 months now the 1.9.3 version of NextGen Gallery.
Till Yesterday everything was OK.
Now, when i open the "Add Gallery-Image" page or the "Option" page nothing appears only white page.
I cannot upload new images or change any option. So i i create a new gallery from "Manage Gallery" (or in existing gallery) and i upload the images from ftp server, but nevertheless NextGen doesn't create thumbnails and i cannot use the "edit" option.
Any idea what happend here because it is very strange and i am afraid if something else happens.
Thanks in advance
