Did you delete /cache/class_index.php?
Sorry, I don't have a cloud setup here, but it seems, you can't not remove that file.
If that's a problem, open a new thread discussing about that.
What do you meany by "Display" anyway?
You're looking for a way to not display these (sub) categories under the main categories?
If so, just simply modify the template category.tpl to hide.
Hope that helps!

As far as I understand,the method Tools::getShopProtocol() is only available on PS 1.5.x and above.
In the other word, this version of module ultimategooglerichsnippets does not support PS 1.4.x.
