Disabling Broken Drupal ModulesEnabled 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
