Yesterday I decided to upgrade the CMS of my website to the newest version of Umbraco to get support for Windows LiveWriter. I used the book  "Install umbraco 3.0 on Windows Server 2003" from the Umbraco documentation page.

If you just upgrade, not all steps are necessary, therefore my steps were:

• Backup files and database (optional but very recommended ;-)
• Install .NET runtime 2.0
• Install MSXML (just to be sure)
• Install Ajax Extensions (just to be sure)
• Copy the files to the webserver (change settings in web.config according to the old web.config)
• Change the website in IIS to use .NET Framework 2.0
• Set up umbraco from the web browser

That was easy und worked fine, but after checking the webpages I found two errors:

1.Error parsing XLST file

At the page displaying blog posts I got the following error:

"Error parsing XSLT file: \xslt\DisplayCategories.xslt"

and at the post page itself

"Error parsing XSLT file: \xslt\WordpressPosts.xslt"

The solution can be found here. Just a small correction in the javascript part and all works fine.

2.Failure when storing the xslt file via web interface

When I then started to change my blogs appearance I got the following error when storing the xslt file:

"FAILURE[object Object]"

That failure was caused by an ownership permission problem. In my case I assigned permissions to the NETWORK user and everything worked fine. A detailed post about that problem and the solution can be found here.
