jQuery Forum

Hi there,
I have a strange problem initing tabs on a container. While everything works on different sites there is just one site things get broken:

tabs() does not find the preloaded panel (after DOMDocumentLoaded) and falls into ajax mode.
First I was thinking that I have made a name or markup mistake so I have tried the simplest: the demo - but with the same result.

I don't unterstand this issue. Everything works fine except this - the jQuery-selector also finds the container manually.
It is a Typo3 generated content (front end)- which I have checked against the W3C validator - but except 3 little mistakes in attributes there is no important error. Also the tab-ui will be generated without problems and
all is working with same scripts in backend.

Any idea whats going wrong here?
I'am currently using jQuery 1.8.3 and ui 1.9.2.

To visualize see attachment.
