Thanks for the update.
I see where the problem was, the theme name has changed to 'pro' dropping the 'x'
It might be as well to mention that somewhere or, as I did, folks will copy the updated files into the current old folder name and not notice a need to change the name, Same for child themes, I had to manually correct names etc. in the styles.css file.
Anyhow, all working now, though sadly there is still the 'A conflict on the front end of your site blah blah blah...' error with a certain plugin activated that alters the permalinks.
