Answer 1

Look at the error itself $connect->error
Yes, and not the fact that it was possible to connect to the database.

Answer 2

Either in the connection to the database, or in this place:
remove such '' quotes and it should work

Answer 3

RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
