Object undefined in jquery, plus my links are pointing elsewhere I asked this question on stackoverflow earlier, not realizing this site existed.  Seems that this would be a better place for it.

In a nutshell, I've restored an existing drupal 7 site under the public_html/migrated_site folder on my hosted site.  

When I browse that URL however I'm getting errors from jquery that the Drupal object doesn't exist, and all my links and images point to public_html/migrated_site/sites/someothersite...

..where someothersite is the name of the old subdierctory under public_html on the prior host.

I changed my settings.conf values to point to the migrated MySQL database, and that bit appears to have worked, in that the site is coming up, albeit unstyled and with the above jQuery and links errors.  

However I'm not sure what could be going on above?  I've tried a few RewriteBase settings in .htaccess in both public_html and public_html/migrated_site (particularly, adding RewriteBase /~hisusersite/migrated_site) but nothing seems to have made a difference.
The Drupal JS object not being defined is a symptom of it not loading core JS files. His previous site probably enabled JS aggregation that places the aggregated file in sites/someothersite/files/XXX.js. The same goes for the missing images. Have you copied over sites/someothersite/ from the previous host? 

It sounds like sites/someothersite/settings.php was what his original host was using and configured for DB &amp; files. Since you're now viewing the site on  gator1111.hostgator.com Drupal is using sites/default/settings.php. 

This primer on drupal multi-site settings might help to also explain what's going on.
