I have 4.9.1 and blog 3.5.  My log viewer show a red line about every minute due to this blog error. My site is very default. I recently did an in place upgrade from dnn 4.5 and the older blog module. Everything works fine, but the log viewer bothers me with these errors. Any ideas. TIA!

Hi Solarspin,

could you please post the entire exception data? You can hide sensible data if you prefer, such as the server's name etc. My understanding is that something is accessing your blog's feed requesting data that is no longer available.

Best regards,
Dario Rossa

Sure, thanks for looking at this! My home page has a RSS feed from the blog page.  I like pulliing the recent entry titles on to the home page.

Here are two errors from the log this morning. Note the user agent on the second one is mozilla, which is not me, so that must be someone from the public looking at the website.

Hi Solarspin,

Best regards,
Dario Rossa

I should only have one blog on this portal. It has 8 child blogs, all kept on the same page. I use them as categories to organize the main blog posts.

I may have created and deleted a seperate parent blog in the past. How do I tell for sure? And if blog zero is not present, can I fix the log exceptions?  I would also like to try and understand if I did something wrong. Thanks.
