    $role = 'author';
    $cap = 'delete_published_posts';
    $wp_roles->remove_cap( $role, $cap );
  • Add A Hint About How Line Breaks Work In The Editor

This a stylish and quite impressive way but some of your clients may find it complex. There are many complain about having a wired white space in post or page after apply the same. You can add an effective snippet to your functions.php file. You need to change the value of $tip to make your author acknowledge of it.# Adds instruction text after the post title input
    function wpmania_edit_form_after_title() {
    $tip = 'TIP: To create a single line break use SHIFT+RETURN. By default, RETURN creates a new paragraph.';
    echo ''.$tip.'';
    This is a nice way to leave a reminder for your clients and they will be careful about while posting or managing content on the site.
  • Do Not Dole Out Administrator Accounts
    Great power comes with great responsibility. The role of administrator is enormous and it has authorization to deal with everything of the theme or site. Some of your clients may have competence to hold the responsibility perfectly but many of them may be less familiar with the interface so they should not furnish with entire power of administrator. In such situation assign them as editor and you will need to create a separate account for admin. Until your clients are ready to manage their accounts themselves, don’t hand over the credentials to them.Similarly you can get the clients the credentials and ask them to keep them safe and use them only when it is required. From previous experience it can be said that many clients will lose the credentials but this is also good for you as because the same client will hire you for getting them back and for routine maintenance. Actually you need to be conscious about the admin account as because they are related to vulnerability and security issue.
  • Use mu-Plugins
    Um-Plugins/directory is another suitable option for installing plugins and fortunately many of the hackers never heard of it. The only one difference is that the ‘mu’ must see plugins cannot be disabled and by default they are active. They usually loaded quicker than other. So most important plugins could be installed here. The mu-plugins have to be created manually inside theWP-Content/.wp-content/
    But there is only one limitation that WordPress only find the files from top and usually ignore codes that exist inside of subdirectory.  You can simply handle this issue by creating a single PHP file that will load at the top of mu-plugins. So mu-plugins could a safe place for codes that will not be accessed by author.

Final Note

You might not agree with the topic of disabling default functionality of WordPress but reality is that having too much editing button actually will not bring your much profit and it could a possible source of pain if your clients try to play with them without knowing them better. Actually your task is to deliver a professional website with robust functionality as well as focus on your client’s requirement. Therefore disabling unnecessary and sensitive functionality actually let you be more professional.
