Drupal 6.22 - Colorbox plugin missing I can't seem to get the colorbox plugin (colorbox-6.x-1.0) working with my Drupal 6.22 site. I'm currently working on Ubuntu Natty, and this is the folder structure for how I have the plugin and module setup:

 - sites
    - all
       - libraries
          - colorbox
             - colorbox
                - jquery.colorbox-min.js
                - jquery.colorbox.js
             - [other folders: content, examp1, examp2, examp3, examp4, examp5]
    - default
       - modules
          - colorbox
             - colorbox.module
             - etc, etc


Other stuff I already have done:


jQuery Update plugin installed
set permissions on sites/all/libraries folder using chmod a+w ~/public_html/drup_test/sites/all/libraries
flushed all caches


I'm still after all of this getting the "You need to download the Colorbox plugin and extract the entire contents of the archive into the sites/all/libraries/colorbox folder of your server" error. Please could someone help me as I don't know what else could be the problem.

Thanks!


EDIT: SOLVED!!

With iStryker's help, I realised that there was some weird permission setting on the /sites/all folder. Whilst I haven't sorted out the permission issue on that folder, this alternative worked (if this has also happened to you)...under /sites/default/ create a folder called libraries and put your jQuery plugins there. Then in Drupal Admin > Administer by Module > Colorbox > Colorbox Plugin Settings, change the plugin path to /sites/default/libraries/colorbox. Not the grandest solution, but it works!  Note that this also worked for the ShadowBox module and plugin.
Revised:

Your directory structure is correct.  Your file directory permissions are not.  Your chmod a+w command gives read and write permissions.  In your case, to get rid error message you must have read and execute permission on the /sites/all/libraries/colorbox &amp; /sites/all/libraries/colorbox/colorbox directories and read permissions on the 2 javascript files.   Colorbox.module does a file_exist call 

if (file_exists($library_path .'/colorbox/jquery.colorbox.js') &amp;&amp; file_exists($library_path .'/colorbox/jquery.colorbox-min.js')) {

Depending on your operating system, and setting, PHP's file_exists() function is handle differently.
