Installing into subfolder

Hello everyone, I’m having issues installing my software into a subfolder on my server.

I’ve already looked at a few posts which are similar, but I’ve changed the .htaccess file to the subfolder, and renamed it with the ‘.’ so it would recognize it as the file. Then I went into the ipconfig.php and change: “IP_URL=” since that’s my website URL, and invoices are my subfolder.

Still get this error:

Not Found

The requested URL /index.php/welcome was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

It appears to be working…
