Fullsize Popup
 

Hello,

if I click an image on showphoto.php, the Fullscreen popup is empty.

If I disable Fullscreen Popups, the image is not displayed at all, instead the Filename of the image is displayed

help is appreciated

In Admin area down the left pane click storage options and hit revert and save twice to load the correct path. Your path is incorrect if your large images are not seen but everything else like thumbs and mediums are. Once you fix that bad path you will be okay.
