someone's blog started not to appear not sure how to figure out why

there is a log 

but doesn't tell me which feed is generating the error?

EDIT... Mis-read post[/b]

Do you have many RSS Blog imports ? If there are only half a dozen or so it would be easier ot view them manually to check to see how they appear in the browser windows when viewed directly. If its more than a manageable number a query can be used to generate a list of them. I'm not immediately aware of a way of making the error log show which is at fault though, this is perhaps something that should be added with say:

 

"Bad XML : Blog ID x" , that way there would be no doubt where the issue stemmed from, at least which Blog.
