I'm having an issue with an existing Piwik install after reinstalling Nginx. After reinstalling Nginx, moving all the files back into place and browsing to our Piwik install I am presented with the message: "Error: Piwik is already installed".
Walking through the code it seems to be getting hung up in the plugins/Installation/Controller.php file during the welcome() function when it does a call to $this->checkPiwikIsNotInstalled() at which point it returns the above message and exits.
What I'm hoping someone may be able to shed some light on is what is the insertion point to start trying to do the install process? I suspect I must have removed a file somewhere along the line, but I really don't want to reset the config and DB table if possible.
