I have created a custom xsl file for the Content Query Webpart. I assigned the path of the xsl file to the property "MainXsl" of the CQW. After I put the CQW to a sub sitecollection, it show me the following message: "The web part references an untrusted XSL file. Only XSL files contained in this site's Style Library may be referenced."
I have checked up, there is my xsl file in the sub sitecollection (Style Library/XSL Style Sheets) and is published.
Please tell me how to solve this problem?
