flickr photo album server problem………………..

I installed the Flickr Photo Album then when I go to the config options it gives me this:

——————————
Permissions Error

This plugin requires that the directory /homepages/6/d152313846/htdocs/ecclesia/wp-content/plugins/
silaspartners/flickr/flickr-cache/ be writable by the web server.

Please contact your server administrator to ensure the proper permissions are set for this directory.

I talked to my server guys and they said that it was an external issue… Did this happen to anyone else??
