First off all I want to thank you for sharing many useful addons to joomla for free.
I noticed problem when adding tag using plugin Button - ARI Doc Viewer.
When I try to add in back-end - I can't see url to file in form (attached file).
What is more when trying to add in front-end - just a black screen - no popup.
Regards,
WS
In front-end when I check link under button there is just # added do address like address.com/#
Added later:
When I am using Chrome in privacy mode in back-end I can see url - but still the same from front-end
