normaly that problem is because your current theme!try going on system admin-template manager
Gallery [List (0)] [Generate]
also it can be because of the template ...
if it is not generated maybe try by generate the template pushing the generate button of wf links module on sistem admin-template manager..if not working on curent default template,try some other template and do the same thing ,
after that go in system admin-module and update your system ,if the problem persist try find another theme like that one...
