 * Hi there,
 * I’m just in the process of setting up a new site for a client and did my usual
   setup of plugins, which by default includes Headspace2.
 * For some reason though I’m getting the following error on attempting to activate:
 * `Fatal error: Cannot redeclare class HSM_JavaScript in /path/to/wp-content/plugins/
   headspace2/modules/page/javascript.php on line 175`
 * This is a little confusing as I’ve never come across this before.
 * I checked through the source of all other plugins installed and could not find
   more than 1 declaration of this class (eg the one in Headspace 3.6.33).
 * So I deactivated all plugins and tried to activate headspace only, and still 
   the same error popped up.
 * I’m developing on someone else’s server so I don’t have the usual command line
   control I have, but I checked out a few things and it’s running PHP 5.2.13 and
   MySQL 5.0.89
 * Any thoughts?
 * Cheers,
    Alex

 * I got frustrated with the clients server, moved to our devel server, redownloaded
   the plugin and activated it without error.
 * Ignore this – must have been an error relating to their server.
 * Sorry!
