Drupal

Drupal is a PHP-based web application framework, similar to Symfony (but also wildly different).

Disabling Broken Drupal Modules

Enabled modules are stored within the database (such as MySQL), so you will need to edit the database manually. To list all the currently enabled modules:

select name,status from system where type='module';

To disable a specific module:

update system set status=0 where name='alfresco_browser' and type='module';

The CTools CSS cache directory, ctools/css could not be created due to a misconfigured files directory.

This refers to the CSS cache directory in sites/default/files/ctools (not sites/all/modules/ctools), and will also occur if the directory exists and a hidden file (such as .svn) already exists within it.

Also make sure that it is group writable and directory executable:

chmod -R a+X sites/default/files
chmod -R g+rwX sites/default/files
