Using the Content Query Web part on MySite
So I was out on client site today attempting to setup the content query web part on a MySite, after exporting the web part and re-importing it to the my site I then got a "Could not load XSL file. The system cannot find the file specified" error. After google failed to provide me an answer I decided to have a play around with the site settings for the MySite and found that if I enabled the "Office SharePoint Server Publishing Infrastructure" site collection features the content query web part started working like a charm. Not only that but if I deactivated the feature afterwards the web part would continue to function normally
