The WordPress version is automatically changed only after the upgrade. If you do not upgrade the WordPress version, the background will always be prompted. How can you remove the prompt without upgrading the WordPress version?
The procedure is as follows:
Open/wp-nodes des/version. php and modify the value of $ wp_version.
For example, set $ wp_version = '4. 0.1 ';
Change
$ Wp_version = '40. 1 ';
In this way, the version number is changed, and the annoying update prompt in the background is removed (the version number is higher than the current version number.
However, it is recommended that you update Pop regularly. Pay attention to major patches officially released.
If you want to keep the current version number and remove the nasty prompt of Wordpress logging on to the background, we need to do this:
Open the wp-adminincludesupdate.php to find echo "<div id = 'UPDATE-nag'> $ msg </div>"; and delete it.
