Sometimes you have to disable wordpress plugins all at once and most wordpress webmaster don’t like going wordpress plugin section and
Disable manually one by one, this looks very boring and annoying.
Here I have real quick peaceful solution!
1. Open you wordpress database in PhpMyAdmin.
2. Open SQL query panel/popup window.
3. Run this command

UPDATE wp_options SET option_value = ” WHERE option_name = ‘active_plugins’;

And it’s done!!
This query will not remove any plugin from server. You can again reactivate your wordpress plugins manually from blog control panel.
You can use this query to make your wordpress blog automated.
