Tabs Plugin in Content

Hi all,

Has anyone implemented a tabs plugin in content. So far I have tried 3 but none works. It must be an incompatibility with some other plugin or something but I don't know how to find out what is wrong. For the record I've tried Tabs & Sliders (Joomlaworks) - no tabs appear, Tabber (Free - NoNumber) - only the first tab appears and another plugin that I don't recall.
Any pointers?

Thanks

Hi

I've been using both this plugins and remember both works pretty well. Please show me Your site.
