We can easily disable all WordPress plugins directly from database. This is useful when some problems with WordPress installation such as not being able to log in to the admin area or having blank pages. To disable all plugins log in to phpMyAdmin and select your WordPress database from the menu on the left and execute this query to disable all WordPress plugins:
UPDATE wp_options SET option_value = ” WHERE option_name = ‘active_plugins';
NOTE: disabling the plugins will not remove them from WordPress application. They will simply be deactivated. We can easily activate them from WordPress admin area.
