I had to move my site to a new host (tinyportalhosting.net) as my old host was unable to solve performance and availability issues with their servers.
tinyportalhosting.net moved the whole site for me to their servers and it all works fine, apart from uploading new pictures via the gallery (individual and batch).
The setting in the admin section is
/home/mmcukcom/public_html/gallery
this folder exists is chmo'd 777
but when I or my users load pictures, they end up in this folder
/home/mmcukcom/public_html/gallery1
this folder exists, is chmo'd 775 and has no subfolders below it
None of the pictures loaded to this actually show up in the gallery, even though they are well below the max size.
All files under the gallery folder, which were there before the move, show fine in the gallery.
