Google SEO Plugin makes the website down

[Hemani]

Hi!

Whenever I add the http://mods.mybb.com/view/google-seo plugin on my forum it shows the blank white page. I already discussed this issue here http://community.mybb.com/thread-149170.html (it was happening due to the above Google SEO plugin)

I need an SEO plugin that can manage. Page title, URLs, robots and Sitemap.

Please help

Thanks
