Re: BUG - Google Bug: Sitemap.php Not Reconised
-----------------------------------
[quote user="Zuker" post="21407"]i don't think it's a bug, in that case, google does not recognise icy phoenix sitemap format. but sitemap it's working almost fine[/quote]

I don´t think google goes change his sitemap robot in order to reconise the icy phoenix boards sitemaps. Althought, it is good builded.
