hostit

just updated to WordPress version 2.9.2 and now all I get is 404 error trying to access either my website or wp_admin page, any idea how to fix??? thanks

thanks a lot that worked fine now back in. Is the reason the fatal error due to the theme not being compatible with the version of WP being run? thanks again.

g’day I uploaded a new theme now i get this message

Fatal error: Class ‘WP_Widget’ not found in /home/hostit/public_html/wp-content/themes/irresistible/functions/admin-custom-nav.php on line 1987

have tried accessing Mysql database as suggested above but there does not seem to be a option to select to change themes.

Can’t access my site or wp-admin page and not sure where to go from here as new to WordPress, please can anyone help!

thanks Nick
