Thread:Project:Support desk/Install the Gumax skin (4.0.3)

Hello there, I need help installing the Gumax skin for my Wiki I host. I downloaded the Gumax skin 4.0.3 from here. I like the version 4.0.3 more than the other (newer) versions. I installed the Mediawiki software two weeks ago and the current version is MW 1.23.4. Yesterday I followed these steps in order to install the Gumax skin. But it doesn't working, if use  or activate the skin as user (preferred) skin. This will appear, if I use the preview: (1) What can I do to solve the problem in order to use this skin without any errors.
