[Plugin: Google XML Sitemaps] Version 4.0beta8 XML blank

Hi Arne, I tried the BETA version and got a blank XML

Our server is php 5.1 and we running wp 3.1.3

Have removed it for now as I am still using a work around method but would prefer to use the BETA version if I am able to get it to work

Thanks
