An adequate CMS integrated with vBulletin has always been a desire for any webmaster to extend content beyond a vBulletin forum. Even after all the products and plug-ins, there are many content management concepts that are found lacking in a stand-alone vBulletin setup.

vbDrupal offers that bridge between a high-caliber CMS and vBulletin. Drupal is considered by many as one of the best, most robust, secure, extensible content management system out there (deemed best open-source CMS by IBM).

Originally post at vbDrupal for vBulletin Forums, used with permission.

When I visit the Settings page I get the following error:

warning: mkdir(files): Permission denied in /.../includes/file.inc on line 91.
The directory files does not exist. 

Drupal uses a single directory for the storage of various files (for example attachments to content). When you visit the settings page it will check if the file directory exists and tries to create it when it doesn't exist.

However if the webserver doesn't have write permission (and it shouldn't) in the directory where the file directory will be created you'll get an error. In order to fix this first think about the name of the directory you want to use. By default Drupal uses the name "files".

Depending on your site layout you might need to change the cookies settings within vBulletin. This page will guide you to the settings you'll have to make.
