Add this below <?php in your config.php file:

define('DISABLE_HOOKS', true);

So now it should resemble this:

<?php
define('DISABLE_HOOKS', true);

Upload config.php back to the /includes folder. Now access admincp, remove the query from the plugin, save and see if your back online .

Comment out the disable hooks when done and re-upload the file!

<?php
// define('DISABLE_HOOKS', true);
