I was able to run the install with no issues. After the install completed, I removed the install.php file and now when I try to go to any page, I get a generic "Internal Server Error".
I went in and put a var_dump($response) on the index page and I noticed the following.
"content": protected => "Internal Server Error"
"statusCode": protected => int(500)
"statusText": protected => "Internal Server Error"
Why would the installer run with no issue but they actual app will not load?
