Sounds like your jquery stuff is not configured correctly and failing to load. Again you need to use browser tools especially the network tab to find out if it is failing to load any files. Make sure you follow the intsructions carefully for self hosting the jquery files, people often miss the part about renaming the file. Once you configure to load jquery locally you need to verify that it is actually loading.

Also the notes about superfish assume that you are using the latest version of mojoPortal, the updated superfish file would not exist in older versions.
