This plugin gives you the ability to disable specific user accounts via a profile setting.
Once installed and activated, a checkbox appears on the user profile settings (only for admins). When checked, the users account will be disabled and they will be unable to login with the account. If they try to login, they are instantly logged out and redirected to the login page with a message that notifies them their account is disabled.
This can be useful in a few situations.
<ul>
<li>You are working on a site for a client who has an account, but do not want him to login and/or make changes during development.</li>
<li>You have a client who has an unpaid invoice.</li>
</ul>

WordPress admin notices and dashboard notifications can quickly become overwhelming. Plugin alerts, theme warnings, update messages, and promotional notices often take up valuable space and disrupt your workflow. Disable Admin Notices gives you full control by letting you hide, remove, or disable admin notices across the entire dashboard.
You can hide all notifications, disable selected notices only, or move everything into a clean compact bar so messages no longer clutter your admin screen. The plugin also lets you disable plugin and theme update notifications, disable WordPress core update alerts, manage which items appear in the admin bar, and even block redirect URLs used by some plugins to show ads or promotional pages.
Whether you want a cleaner dashboard, fewer interruptions, or complete control over WordPress admin notifications, this plugin helps you keep your workspace organized and distraction-free.
