Hi there,
Thanks for all the responses - you missed one question that actually could be the cause: are you using a custom theme plugin, and/or have you made any code changes or customizations in your AtoM instance?
Additionally, one of our developers has suggested that you check the browser console to see if there are any useful error messages captured there. If using Chrome, you can do this by:
- Navigating to browse or view page (any page with a clipboard button that isn't working
- Right-click somewhere on the page, and select "Inspect" from the context menu
- A pane will open up - at first, it will likely be displaying the HMTL and CSS from the page you are viewing
- There should be tabs at the top of this pane - click over to the one that says "Console"
- Now, while watching the console pane, try adding a description to the clipboard
Is any error message registered in the browser's console pane during this operation? If yes, please share it with us.
