When Liferay is relocated (using portal.ctx=/foo in my portal-ext.properties) and deploying the Liferay web app to /foo, the welcome theme is broken - none of the images show up (see attachment). I believe this is because of the hard-coded values in the web content article representing the front page (e.g. "WHAT WE DO" article).
BitNami uses a relocated Liferay in their Liferay distributions - as they are a major redistributor of CE I have marked this as major and am interested in any known workarounds (if any!).
