I've been getting an error from google for a while now, saying that my sitemap is not a valid format.
I was also getting an error on my older sitemaps from my index, saying that there was not enough memory (I couldn't get a screen shot).
I tried to disable all my plugins and activated the seveneleven theme, but kept getting the same error.
But since yesterday I can't even find my site's sitemap ( http://room187.com/sitemap_index.xml ). It says page not found.
Is there anyone with this same problem?? Oh and by the way I'm using:
WordPress version: 3.4.2.
WordPress SEO version: 18.104.22.168
