Is onlink-mod.net supposed to have all sorts of MySQL errors?

Example: Downloads page.

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'miah_general'@'localhost' (using password: YES) in /home/miah/public_html/onlink/includes/download.php on line 2

Warning: mysql_select_db() [function.mysql-select-db]: Access denied for user 'miah'@'localhost' (using password: NO) in /home/miah/public_html/onlink/includes/download.php on line 3

Warning: mysql_select_db() [function.mysql-select-db]: A link to the server could not be established in /home/miah/public_html/onlink/includes/download.php on line 3

Warning: mysql_query() [function.mysql-query]: Access denied for user 'miah'@'localhost' (using password: NO) in /home/miah/public_html/onlink/includes/download.php on line 13

Is this jsut my computer, or is this a serious issue?

Er... huh?

I see it fine. Try clearing your cache.

Yeah, okay. It works fine now--I still don't know why it did that. Clearing the cache didn't help at the time.

maybe someone worked on the site at the time you loaded it and the error page got stuck in your browser cache.
