Press75.com Site Goes Down and Crashes WP-Admin (3 posts)

    Press75 vidley's theme (and probably most other themes) have an update-notify.php script that makes every wp-admin page unaccessible if the script cannot contact press75.com (which was the case in the last 30 minutes as their site IS down: http://www.downforeveryoneorjustme.com/press75.com).

    the log shows [warn] mod_fcgid: stderr: PHP Fatal error: Cannot use object of type WP_Error as array in /var/www/vhosts/mysite.com/httpdocs/wp-content/themes/vidley/update-notify.php on line 41

    below is the code for "update-notify.php". what improved error handling structure would you implement to it?

    In the beginning of the file, just comment out this line of code:

    add_action('admin_init', 'un_periodic_update');

    Change it to:

    /*add_action('admin_init', 'un_periodic_update');*/

    Problem fixed.

    thanks, but thats not "problem fixed" :) thats a dirty workaround which happens to be the first thing I did to get the admin back up.
