It seems every time I check on the sitemap created by WordPress SEO by Yoast, I have to hold my breath, because I know it's probably not going to be working for some reason.
Today when I checked it, I got this error:
XML Parsing Error: no element found
Line Number 1, Column 1: ^
So, once again, there is no sitemap available. In the past, it's been other things that caused it not to work. It seems to be very fragile.
How can I correct this error, and make the sitemap more stable?
