Three small files of code and MASSIVE framework which was definitely not intended for use with regular web hosting.
I see you’re not using my recommended .htaccess snippet, and appear to have butchered Laravel’s directory structure to make your website work. Next to the fact that this is a huge security problem (seriously, you should update any passwords currently configured in your application), this is a rabbit hole to fix.
I had this discussion a few weeks ago with someone else who had trouble running Laravel. Maybe some of the information there can help you too?
