Hi, I've spent a lot of time getting a
site right for a customer on my dev server.

I've moved the concrete5 directory to the
live server now but a couple of blocks i got from the marketplace aren't showing.
Namely: iFrame and superfish

If I go to add functionality->edit->edit->refresh i get:
"not found. Please check that the block controller file contains the correct class name." even though everything is there just as before.

Do I really have to reinstall these and go through the whole site adding them and their content back in? Or is there another way?

Thanks,
Pete.
