[osCommerce] Error message: unable to initialize cache

[PosterExpo]

I have Zen Cart and magic seo was working fine. I have since moved to a new server and get this error message at top of page:

Warning: Magic SEO URL was unable to initialize cache. This may results in SQL server overload! Please make sure fancy-data directory writable.

I have no idea what it means please help. You can see site at http://www.posterexpo.com

Please make cache/fancy-data/ directory writable for scripts.

P.S. Do not make duplicate support requests via email and board, choose only one way.
