Backup module will not run backup

I cannot run a backup. When I attempt to run backup the model windows opens and no text appears, just sits there.

I have rebooted
I have uninstalled, removed and reinstalled the module.

No changes.

I have confirmed I can run the backup via terminal.
cd /var/lib/asterisk/bin/
php backup.php --id=1

seems to work just fine, received email etc…

Tried again via gui and it still doesn’t work.
