Upgrade Script?

I just finished upgrading our site to 3.40. When downloading Smart theme, there is a zero byte (empty) upgrade script for upgrading to 3.4. After upgrading my product ribbons nor ajax filters seem to function.

Hi jburke,

This time our upgrade script is empty. We have left it for consistency only as almost every upgrade you need to run it (no matter if it is empty or not).
Are you upgrading from 3.3 to 3.4?
You need to uninstall and then install the Ajax Filters plugin as described in the upgrade steps.
I don't see any reason why the Ribbons are not working. Please let us know what exactly is not working with the Ribbons?

Thanks
