[Plugin: Google XML Sitemaps] Sitemap shows blank and doesn't run. Over 1GB of memory available

Not sure why but the sitemap on hairwegoproducts.com isn’t working. Was hoping that someone could assist me in troubleshooting.

Max execution time is 90 seconds and there is 1GB of memory available. I’m on a dedicated server which I manage. The sitemap works on other sites I’ve installed on the server.
