I have upgraded to 2.2 and updated the colorbox plugin with the latest version.. The "Status" report page is clear but I am getting the following warning message..
Warning: file_get_contents(sites/all/libraries/colorbox/colorbox/jquery.colorbox-min.js): failed to open stream: No such file or directory in drupal_build_js_cache()...
If I move the jquery.colorbox-min.js file to libraries/colorbox/colorbox/ then the warning goes away but the status page shows a problem..
So I had to put jquery.colorbox-min.js in both the libraries/colorbox/ and libraries/colorbox/colorbox/ directories to make the warning disappear and the status page happy.. I am not sure if the file is now being downloaded twice by the browsers from each location..
Any ideas why this is happening?
