[Motion Picture Theme] Publicly displaying error messages.

Hi, I have a site which uses the Motion Picture theme by Obox. I’m not sure if this theme is still supported? I’ve contacted Obox but the information on their site is inconsistent, so I’m also posting here in the hope that somebody can help.

Presently, if you visit my site there are a series of publicly visible MySQL error messages at the top of the page, breaking the site layout and causing loading problems. They also reveal confidential data. So the problem is urgent.

The error messages refer to legitimate human login errors from earlier in the week, but I have no idea why they are manifesting publicly? They also appear on the wp login page.

If anyone has any ideas what could be generating these messages and how to remove and prevent them, please advise?

I have checked that the wp-config.php has the WP_DEBUG set to false.

I have also deleted the error_log.

The errors are to the effect of

Warning: mysql_query(): A link to the server could not be established in…

and

Warning: mysql_query(): Access denied for user…
