FAQ
-
Will this block all types of admin notices?
-
Yes — the plugin intercepts WordPress admin notices regardless of their source (core, plugins or themes).
-
What happens to notices after I hide them?
-
They are stored in the Hidden Notices tab where you can preview, restore, or keep them hidden.
-
Can I temporarily hide a notice?
-
Yes! Use the snooze option to hide notices for a specific time period (1, 3, 7, or 30 days).
-
No, once hidden, notices stay hidden until you manually restore them.
-
Does the plugin impact front-end performance?
-
Not at all. Notification Blocker only works within the WordPress admin area and has no effect on your site’s front-end.
-
Can I choose how the plugin’s interface looks?
-
Yes, there’s a UI Settings tab that lets you choose between WordPress default styles or a custom UI.
