I recently updated jAlbum and the Tiger skin. In the last two galleries I created (this past Sunday), I see the 1:1 button when I preview the galleries through jAlbum, however once they get uploaded to the server, the following occurs:
Viewing in Safari, the 1:1 button has disappeared altogether. It's the only one that doesn't show, the rest are ok. See here:
In Chrome, the button is there initially, but if I click on it to change the image size, it also disappears at that point.
I never had this before. I began using the Tiger skin in late-2019 and in the time since, I've recreated dozens and dozens of my galleries going back to 2004 and they all function perfectly. So something has changed since the updates I made.
And in case you're wondering, in the parameters for the Control Bar, I DO NOT have a check beside "Hide the "fit screen/1:1 button". I never had this checked before as I like that option for my visitors.
