Greetings all!
I'm not entire sure what Sellacious is - but I didn't think it would take over.

I went ahead and installed Sellacious on my website thinking; all I have to do is create a menu item that directs it to Sellacious just like most components. I'm unsure if I did something wrong... but immediately after install, I was no longer granted access to the frontend of my site. Like, it was completely taken over. Nothing but a red error screen.
Thankfully, I was still able to access the backend to do a full uninstall and brought back my site.
This may be a dumb question but I've never had such thing happen before - so I ask; does Sellacious require a joomla site to be all it's own and nothing else? Or can you actually add it to an already established website?
