As I don't have any image gallery content - as I removed due to these issues - I deleted remaining image-gallery folder, and went to add a new Image Gallery page... bam up comes that error. Can't access the image gallery page or do anything with it. When I checked is any folders had been created, it had created:
image-gallery
image-gallery/NewImageGalleryPage/DefaultAlbum
new-imagegallerypage
All these set to 755 with User as (?) and Group as (?)
YET if I go to Files & Images I CAN select these folders and drill-down on them!
However these folders display in italics yet my Uploads folder is not. What does a folder name in italics signify?
