RE:Creating blog posts error
Hi Sahus,
Could you please check the database table: CONTENT_Blog? The standard one from 4.0 version contains column: BlogModerators and it seems your one is missing it.
Best regards, Helena Grulichova

RE:Creating blog posts error
Hi Helena,
I checked the SQL table for CONTENT_Blog and your right there is no column for BlogModerators. How should I go abouts fixing this problem? Create a new column? What is your suggestion?
Kind regards,
Sahus Pilwal

RE:Creating blog posts error
Hi,
It seems that you have upgraded the CMS before. It is possible that the SQL script was not executed successfully and the DB is missing some columns. I will sent to your e-mail address export package with the blog document types, so you can import it to your CMS and the DB tables should be updated. I am sorry for this inconvenience.
Best Regards, Juraj Ondrus

RE:Creating blog posts error
Hi,
No I believe I started new from version 4.0. I have received your e-mail with the export packages. I will run these on our development server first to see if it is fixed then publish to production server.
I will let you know if this resolves the issue. Many thanks for your help so far!
Kind regards,
Sahus Pilwal

RE:Creating blog posts error
Hi,
Could you please tell us which version of Kentico CMS do you use? You can access the DB using MS SQL Management studio interface.
Could you please check whether the table CONTENT_Blog contains column named BlogModerators?
What was the recent change in your CMS before this error?
Best regards, Juraj Ondrus

RE:Creating blog posts error
I'm using version 5.0 of Kentico CMS. The CONTENT_BLOG table doesn't have a column named 'BlogModerators'.
This is the first thing that i tried to do with the CMS i.e. created a blog module and tried to insert a blog-post. Please guide me how to resolve the issue.
Thanx

RE:Creating blog posts error
Hi,
Was your CMS upgraded before? This field/column was added in 4.x versions. To fix this issue you can simply go to Site Manager -> Development -> Document types -> edit Blog type and add field with attribute name BlogModerators.

RE:Creating blog posts error
I'm not sure if the system was upgraded or not. I've stepped into this role for the client.
So I followed the steps from http://www.kentico.com/Docs/DevGuide/index.html?adding_blog_to_your_site.htm and received the error that started this thread. I followed the steps you provided to add the blog moderators field. That solved it to this point.
Thanks Rick

RE:Creating blog posts error
I was sent an import script to fix this. Once I applied it, the blog started to run smoothly.
I'll try and find it for you.
KENTICO is my new favorite CMS.

RE:Creating blog posts error
Hi,
I would recommend upgrade to newer version - at least to 4.1. I think it might help. Also, the script mentioned above - if I found the correct e-mail, it was a document type object export package but anyway, it was for version 5.0 - you will need to upgrade to this version too. I am sorry for this inconvenience.
