I have just installed the metaPost module and tryied to configured it from WLW.

I get this Error 0:

We tried everything, but weren't able to identify a Valid dotnetnuke portal based on the URL you provided. If you are referencing a child portal, please include it in the URL.

Any idea on what is happening?

Thanks

Thanks for you help Don.

I resolved the problem. I discover where the problem is through the EventLog viewer. It was showing this error message: 

EXCEPTION: Access to the path 'I:\FerozoWebHosting\digitalsolutions.es\public_html\SiteUrls.config' is denied.

So I corrected the impersonate user rights of my hosting provider. Now It´s working fine.
