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:
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
