Can not write to file-system [#1144138]

I cannot start up boost due to this error shown in the Status Report:

Boost	Can not write to file-system
Directory /var/customers/webs/Webmaster/jail4judges.info/cache/perm/www.jail4judges.info credentials - Permissions: 0750. Owner 10002. Group 33.
Your credentials - Group ID: 33. User ID: 10002. Current script owner: Webmaster.

I do not get this. The credentials match the persmissions on the file, the Group ID and Owner is the same. I have executed the commandchown -R Webmaster:www-data . from the root of the site, where www-data is the user name and group PHP runs under. This should have made sure PHP has the same credentials as Webmaster.

Group must be able to write, set permissions to 766

if still doesn't work try setting to 777

Boost failed to create the cache directory.
The Drupal directory owner/group was the main account on a multi-site install, which works normally well for all sites and modules.
I had to create it myself and set www-data as owner, 766
