Advanced Frontend Editing

In FireFox 3.5.5 after getting the error:
The requested URL
/defVals[tt_content][CType]=image&defVals[tt_content][imagecols]=2 was not found on this server.

was succesfully removed by disabling the admin control panel I now am directed back to the start page of the website when clicking on the editing bar accross the top. There is a javascript error on the page: typoSetup is not defined. Here is the code generated:

TYPO3.LLL = {
                feeditadvanced : {"dropMessage":"Drop content here","loadingMessage":"Loading editing form"}},

/**
 * TypoSetup object.
             */
            function typoSetup()    {    //
                this.PATH_typo3 = TYPO3.configuration.PATH_typo3;
                this.PATH_typo3_enc = TYPO3.configuration.PATH_typo3_enc;
            }
             var TS = new typoSetup();</script>

The last line above is what generates the error code. Perhaps there is a syntax error someplace, but I could not find it. (don't do javascript very often)

When clicking on the content element edit button the lightbox pops up, but there is no content in the box. Attached is a screenshot of the lightbox pop up.
