 * My Publish, Category, Tags, and Featured image tabs all feature a php error with
   a code like:
    ‘Warning: call_user_func(post_submit_meta_box) [function.call-user-
   func]: First argument is expected to be a valid callback in /home/a7844083/public_html/
   wp-admin/includes/template.php on line 975’
 * meaning I can’t publish any posts, or do anything really. Could I get some help?

 * Check your site for malware at:
 * [http://sitecheck.sucuri.net/scanner/](http://sitecheck.sucuri.net/scanner/)
 * And prove beyond truth that your own computer has not been compromised (It is
   clean?).
 * Then, switch to default theme, deactivate all plugins…

 * Anyone can make an image…if not a live site we can likely do very little to support
   you.

 * Please deactivate plugins one by one and change theme to default to make sure
   it’s not a plugin or theme related issue. I assume a function in plugins or theme
   caused the warning. Maybe it’s a custom function for post meta box related functions.
