I followed this tutorial https://wiki.hybris.com/display/R5T/Creating+New+CMS+Components#CreatingNewCMSComponents-Addthenewcomponent
In order to create custom CMS component in Hybris 6.5. Funny thing, after restarting Hybris, the default b2b site I had before is now gone (redirected to HAC page). I even didn't start using the custom component in my impex.
What's going on?
