Crap, I just hit the solved checkbox by accident. This didn't solve the issue. When I added them I got this:

Did these DLLs specifically come with the blog4umbraco install? Or did the umbraco.editorControls.dll come with the core?

I should also note that I recently upgraded from 4.5.1 to 4.5.2. The blog4umbraco was installed prior to the 4.5.2 upgrade, but I did not start working with it until after the upgrade; therefore I can't tell for sure if it is a result of the upgrade, or already existed prior to it.

Oh, and I forgot to add: both of the DLLs umbraco.editorControls.dll and Umlaut.Umb.Blog.dll are in the bin.

Looks like you're running umbraco 4.5.2? You need to remove the bin from the path in xsltExtensions.config

Well, that got me a bit further, but now I have the following issue:

Do you have a comment table in the database? Might have to reinstall if not.

I see that in the cs file now. And no, I don't see one of those in the database. Or any other tables that look like they are referenced. Hmmm, I've already done a re-install once and it didn't add them. Any one happen to have the SQL for creating those tables. I'd rather just run that to fix it as re-install did not seem to add them.

Never mind; I found it:

CREATE TABLE [Comment](
[id] [int] IDENTITY(1,1) NOT NULL,
[mainid] [int] NOT NULL,
[nodeid] [int] NOT NULL,
[name] [nvarchar](250) NULL,
[email] [nvarchar](250) NULL,
[website] [nvarchar](250) NULL,
[comment] [ntext] NULL,
[spam] [bit] NULL,
[ham] [bit] NULL,
[created] [datetime] NULL
CONSTRAINT [PK_Comment] PRIMARY KEY CLUSTERED ([id] ASC));

Thanks for all the help.

Tim sounds like your install of Blog4Umbraco went horribly wrong somewhere, looks like it only install half the stuff. Great job on patching it all back together though and for recording it all here. Excellent Umbraco "can do and will share" mentality.

is working on a reply...
