when I hit the “folder-structure”-symbol I see a pop-up saying “Please wait…”
It will take some time to generate full tree if you have 50+ folders and it will fail if script execution time is set too low.
You can disable simple_copy_move option (set to false inside index.php) and use cut/copy/paste model without folder structure tree.
This can also happen if you don’t have standard PHP libxml extension installed because FileGator relies on DomDocument class to generate tree view.
