It looks like there were a couple of issues going on. In the ticket you posted that you tried renaming the configuration folder and did not get the proper results after doing this. You then updated the ticket to say that after renaming the config folder you then had to delete the cache file to get things working without the js errors.
I noticed that there is no link to the steps for deleting the cache file so I'm adding the link here:
