sitemap.xml is a 0 byte file

[chris29]

Installed Unlimited Sitemap Generator - (Standalone Sitemap Generator (PHP) v2.8, 2007-12-27)
Text, ROR & HTML sitemaps are fine
XML sitemap is coming up as 0 bytes
The file modification date and time of sitemap.xml is as expected (same as others i.e text and html sitemaps) but has no content at all and is 0 bytes.

Have checked file permissions, which are fine
Please Advise

Thanks in advance
