Hello,
This issue happens in Safari, not Firefox (not tested in other browsers).
But there is an update for Safari that is not installed yet.
Unfortunately I will not be able to test after the Safari update as I managed to update the apps in Firefox and the version status is not iddle in Firefox...
Here is the description of the issue I encountered:
1. The version check runs iddle
2. The "Add file" button is not responding
3. There is a link on the "Please choose a file" heading text in the popup window. This link opens the file explorer but does not display the selected file in the popup window.
4. If trying to install then a blank page with the following displays:
Warning: Invalid argument supplied for foreach() in /.../administrator/components/com_jbusinessdirectory/models/jbusinessdirectory.php on line 798
