What was your solution? 

Hi BenH

What version of Umbraco are you using? And what is the exact error you're getting? The solution Biagio found 4 years ago may not be the same today nor the issue.

Hi Jan, 

I'm using 6.2.1 (business not Blog4Umbraco) and the exact error is: 

System.Xml.Xsl.XslLoadException: Prefix 'TagsLib' is not defined. An error occurred at D:\Staging2014\xslt\635586379038769721_temp.xslt(16,1). 
at System.Xml.Xsl.XslCompiledTransform.LoadInternal(Object stylesheet, XsltSettings settings, XmlResolver stylesheetResolver) 
at umbraco.presentation.webservices.codeEditorSave.SaveXslt(String fileName, String oldName, String fileContents, Boolean ignoreDebugging)

I've also added the ext line to my config file (found here http://our.umbraco.org/documentation/using-umbraco/backoffice-overview/property-editors/built-in-property-editors/Tags)

Is it because I'm not using the Blog version? 

Thanks! 

Hi Ben

Ok, perhaps you're simply missing a namespace in the XSLT file.

Could you please post the XSLT code and the content of your /config/XsltExtensions.config file?

Hi Ben

Ok, seems like you need to add a namespace reference in the xslt file in the line where you see the other ones like xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" so you should add xmlns:TagsLib="urn:TagsLib" in that line somewhere as well and in the exclude-result-prefixes attribute you should add TagLib as well.

Hope this makes sense :)

That did something! Got a new error:

Hi, Ben,

I'll search into the code of an old website that I port to the last version of U6 branch.

is working on a reply...
