Fatal error with the tagadelic module I have this error after the installation of the tagadelic 7.x-2.x-dev module:  


  Fatal error: Call to undefined function tagadelic_get_weighted_tags() in /home/www/2374fcf941c82d5986ed6d27587b81e0/web/sites/all/modules/cumulus/cumulus.module on line 120


How can I recover my site?
Log in to your database panel (for example PHPMyAdmin) and run following query:

UPDATE system SET status='0' WHERE name='tagadelic';


Additionally, if you are using Drupal 7, run:

DELETE FROM cache_bootstrap WHERE cid='system_list';


After then you can uninstall problematic module via administration panel.
