Edit your index.php.
find:
PHP Code:
$result_quote = $DB_site->query("
SELECT * FROM quotes WHERE approved=1 ORDER BY rand() LIMIT 1
change to:
PHP Code:
$result_quote = $DB_site->query("
SELECT * FROM ". TABLE_PREFIX . "quotes WHERE approved=1 ORDER BY rand() LIMIT 1
That's the only place i could find where the coder missed a table prefix, for the rest all looked nice coded.
