Disable update tips from wp-admin page in WordPress site

Question

How can I disable update tips from wp-admin page? My WordPress wp-admin page showing this warning:

An automated WordPress update has failed to complete - please attempt the update again now.

But "Update" section of "Dashboard" shows that my WordPress, theme and plugins are up to date. How can I remove this warning? Also help me to completely disable this type of tips from my wp-admin page.

Answer 1

This message is generated from a file called .maintenance in the root of your WordPress installation. To remove the message you simply need to delete the file.

Edit: To remove all udpate tips from now on, paste the following code in your functions.php file:

if ( !current_user_can( 'edit_users' ) ) { add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 ); add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) ); }

This code will remove all update notifications for all the wordpress users with rights to edit other users (usually administrators)

Answer 2

This filter is sufficient for Wordpress 3.0:

add_filter( 'pre_site_transient_update_core', create_function( '$a', "return null;" ) );

For 2.8 to 3.0 use this:

remove_action( 'wp_version_check', 'wp_version_check' );
remove_action( 'admin_init', '_maybe_update_core' );
add_filter( 'pre_transient_update_core', create_function( '$a', "return null;" ) );
