Using Mediawiki 1.14, I installed gumaxv-1-0 : when using Mediawiki's default skin, I see in the left column, a search box and some options under Toolbox. When I switch to gumaxv, I see SEARCH, TOOLBOX and LANGUAGES but no options under those items.
Looking in Monobook.php, I noticed they have developped functions to display those items (at the end of the script). I think gumaxv (and gumaxdd) should be modified to something similar to Monobook.
Other than that I'm happy to see your template supports Fckeditor
Searchbox and toolbox problem
Re: Searchbox and toolbox problem
Remove these three SEARCH, TOOLBOX and LANGUAGES from the MediaWiki sidebar...
