I'm running uBlogsy 3.0.1 in umbraco 6.1.6. all had been going swimmingly until yesterday, when I started getting multiple NullReferenceException errors. On the landing page for the blog, the error is

On blog post pages, the error is:

The only change that I can see is that someone added a new blog post (the second in the new year, if that matters).
I had the same problem and it seems to originate with the PostService not being available.
I restarted the website (by editing the web.config file). It doesn't answer why the problem occured but it made it go away, at least for now.
Edit: It came back the next day so this is not a fix.
I've the same problem!!!!!! How solve!!!! Where is the author?
I tried to edit web.config and site start working again!!! But how solve this?????? Which is the problem????
No crash again:
