Re: Sidebar Tabs
@janismo – do you mean widgets aren’t working in your sidebar? Or, do you mean specific plugins for displaying the widgets in tabs aren’t working?
If it’s a simple problem adding any widget, then try with the default theme, disable other plugins, and see if the problem still exists. [note: in general, if you have a widget / plugin that is supposed to be compatible, but isn’t working – it’s a good idea to strip back to basics and try to identify whether it’s something in your theme, or perhaps a clash between two of your plugins]
If you want to create tabs manually, you are best to look at some of the Javascript libraries, e.g. jQuery, that have components already built for creating tabbed interfaces. You would then edit your sidebar.php template file to ensure your components are added, and that the markup is correct for the Javascript tabbing script.
