 * I am back from travel. Concerning your first question around the javascript error,
   I ran some tests on my local installation and am not getting this error. Since
   you are working in a local installation, can you deactivate all plugins, except
   for Bug Library, and see if the error still occurs?
 * Also, when you say that you have the latest jQuery, did you specifically modify
   your theme or installed a plugin to load the latest jQuery? It is always recommended
   to not install plugins that load their own version of jQuery, as most plugins
   are written to work with the one that is delivered inside of WordPress itself.
 * Concerning your bugs not appearing, could you perhaps send me a screenshot of
   the bug in the editor so I can see how all fields are set? I just did a test 
   for this as well, and as soon as I save it, it appeared on the site. Are you 
   using performance plugins that might not refresh your page content immediately,
   until you clear the cache?

 * Thankyou for your time. I just downloaded the colorbox.js [here](https://github.com/jackmoore/colorbox),
   so now its working fine Im not sure why you dont face the same issue but here
   the colorbox.js is required and its not loaded from plugin I included the file
   in theme and worked.
 * Thankyou again.

 * also replaced line 2418 to
    $output .= “<script language=’javascript’>”;
 * and 2432 to
    $output .= “</script>”;
 * just changed the script to lowercase, there was a div issue I know its strange
   but this solved the second issue too.
 * Thankyou for the plugin.

 * Is it possible that you theme does not have a call to the wp_head() function?
   I do not understand why the colorbox script was not getting loaded in your site.
 * I made the corrections to the script tag that you indicated.
