Collections share menu not working

[robergej]

Hi,

I'm using LinuxServer's Piwigo docker image, with Nginx reverse proxy to serve piwigo on HTTPS, Raspberry pi 4, Arm64.

When User Collections is enabled, This works fine:

• use the Collections menu, see my collections and click on pictures
• clear collection
• delete collection
• Create new empty collection
• add an entire album to a collection

But this stuff doesn't work:

• When viewing the collection, edit, share, and send collection buttons don't work. They each redirect to their appropriate URL:
  • https:///index.php?/collections/edit/1#edit_form
  • https:///index.php?/collections/edit/1#share_form
  • https:///index.php?/collections/edit/1#mail_form
  • But nothing happens on screen. No form is shown.
• In the photo view:
  • Add to collection button (star) doesn't work. Nothing happens, no URL change
  • The 'size picker' button doesn't work anymore. This button works fine once Collections plugin is disabled.

Thanks for any suggestions, let me know what more info I could provide.
