Just moved the gallery to a new host, I did the db export/import, updated config.inc.php, changed the rights to 777 to the albums (and subfolders) and include folders.
If I set the upload method to single file, I can upload an image.
But if I set the upload method to multiple files, on upload I get an error message: "Impossible to move."
How can I fix this?
Oups, I hadn't set the albums/edit folder to 777
Seems to be working now.
