Zenphoto 1.6.4
If in Admin I use the TAGS tab, I can create a Tag.
If, from the front end, viewing an image or an album, I click Admin and edit image, I get the mechanism for creating a new Tag plus list of existing tags but, on clicking Apply, no new tag is created or applied - same if I select edit this album, then images and try to do a batch addition of a tag - it goes through the motions but neither creates nor applies no tags.
Thank you,
Richard
