My forum at www.sloe.biz/pip/ seems to display correctly. And I can login as myself. But when I click the ACP link at bottom of the page I get this error:
My new host suggested:General Error
SQL ERROR [ mysql4 ]
Access denied for user ‘xxxxx’@‘localhost' (using password: YES) 
An sql error occurred while fetching this page. Please contact an administrator if this problem persists
I do have full access to my cPanel. What steps should I take to create a new user, and update config etc? Or any other ideas Please?It looks like you are using the main cPanel/DB user to connect to the database. If your cPanel password has ever changed, then this would have stopped working.
I would suggest creating a new DB user through cPanel and updating your site's config files to reflect this.
