That's a bug with Clearspace on Resin (http://www.jivesoftware.com/issues/browse/CS-986), fixed already and will be shipped with Clearspace 1.1.1. You can fix it right now by editing /admin/user-create.jsp in your webapps/clearspace directory. Move the:
<%@ taglib uri="webwork" prefix="ww" %>
<%@ include file="include/global.jspf" %>
Worked perfect, thanks!
I would like to install Clearspace on Resin on Linux CentOS 4. I am on the usual Cpanel/WHM infrastructure. Would you mind sharing some information on how you got to installing the whole thing? Thanks!
