I deleted an existing website and tried to Install Wordpress + LS Cache on the same domain
and got this

Entered a simple password without any of those unacceptable charactersas, and it still won’t install, but gives me the same message.
Is there a problem trying to recreate a blank wordpress site on the same domain?
