I just installed GJ 2.4 in a J!1.5.25/CB1.7.1 site, PHP 5.2.17 on Joomlashack Onyx template. The labels on all of the integration tabs are placed below the tabs themselves on the active tab and invisible on the other tabs, as shown in this picture. It's a conflict of some kind with the template, but I can't find the exact cause. It displays properly in all the other installed templates. Where to look?
