For security purpose I want to Disable the adresse below:
It's give informations about the version of wordpress used.
You can actually do this on the web host without actually any PHP code. Using the same procedure as is recommended to deny access to
wp-config.php, you can also deny access to
All you need to do is create a file named
wp-admin and put the following in it:
<files upgrade.php> order allow,deny deny from all </files>
What this does is it tells the web server software do deny access to
upgrade.php from everybody. That way if someone tries to access it, the server will return a 403 error instead.
This assumes your web host is running Apache as its web server software. If it is not, their support staff should be able to assist you.
