Hi,

I'm maintaining a Umbraco installation on a shared hosting managed by a Plesk Control Panel. The version is "umbraco v 4.0.1 (Assembly version: 1.0.3373.718)" and the Hosting is ASPNET 2.0.

There seems that Plesk CP has some issues and the site suddenly ran into problems. After I restored privileges I start having an issue that I didn't have before with the XSLT files. They haven't been changed or anything has not been published in a while. So I don't understand the nature of this issue.

The debug of any page in the site throws an error like:

Error parsing XSLT System.Xml.Xsl.XslCompiledTransform
El valor del atributo'order' debe ser 'ascending' o 'descending'. Error en C:\Inetpub\vhosts\XXXX\httpdocs\xslt\ListNewsEventsOnHome.xslt(36,1).

We didn't change any code so I don't understand what is the issue here. Why it was working before and now is not.

Any pointer will be very much appreciated. Regards, Victor
