I have installed the script and I have added the redirect line to the .htaccess file as suggested. However it still doesn’t prevent someone from running the setup again. Any Ideas? My .htaccess file looks like this.
But I can still access the link: http://mydomainhere.com/invoice/setup/ and the setup resets the installation like it never happened. Huge security hole in my humble opinion if we can’t figure this out gang. Please and thanks ahead of time for a solution that will fix this.
