uBlogsy - Bugs

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

Source Error:


Line 46: 
Line 47:     // show each post
Line 48:     foreach (var n in posts)
Line 49:     {
Line 50:         @Html.Partial("uBlogsy/Landing/uBlogsyLandingShowPost", new ViewDataDictionary(ViewData) { { "Node", n }, { "GravatarSize", 40 }, { "ImageWidth", 300 }, { "ImageHeight", -1 } })

Source File: c:\inetpub\etc-umb-616\Views\Partials\uBlogsy\Landing\uBlogsyLandingListPosts.cshtml Line: 48

On blog post pages, the error is:

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error:


Line 18:     var month = Request.QueryString["month"];
Line 19:     var day = Request.QueryString["day"];
Line 20:     var prev = PostService.Instance.GetNextPost(Model.Content, tag, label, author, searchTerm, commenter, year, month, day);
Line 21:     var next = PostService.Instance.GetPreviousPost(Model.Content, tag, label, author, searchTerm, commenter, year, month, day);
Line 22: }

Source File: c:\inetpub\etc-umb-616\Views\uBlogsyPost.cshtml Line: 20

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.
