I installed this module, published it, and my site crashed. I know it was this extension as when I unpublished it, the site came back. I have now uninstalled the extension, but my site is EXTREMELY SLOW. Will probably have to re-build from scratch. Not sure what happened, but it seems to be directly related to this extension. Very disappointed...
I am sorry but your assumption is incorrect since when you uninstall a extension all its files are deleted. This is how Joomla works. If you would have opened a ticket we could have told you this, but instead you are trying to damage our business buy giving us a bad review for now reason.
