Cannot expand pictures to show full screen for guests

[MondyNor]

I use this theme, but i have this problem with it. As long as i'm logged in as a user i can view my pictures full screen by touching the fullscreen gadget, but if i use the same browser (i've tested this with Edge, Chrome and Firefox) not logged on the fullscreen gadget has no effect.

I've found no way to adjust this in Piwigo settings for the guest account nor in the theme settings.

So is the theme made like this by intention or have i found a bug? Regardless of the answer, can it be fixed for me so it works as i want, i don't want people registration just to see my pictures.

I think i have narrowed this problem down to the photoswipe-ui-default.js file, sadly i don't knoe anything about java scripts to fix this :(

Apparently this has been fixed in the Revision 2.5.17 :) Thanks a lot, now my gallery works perfect even for guests
