Sellection different Tab Types doesn't show any info

I tryed this in the garland and a custom theme
Have quicktabs on another site, works fine.

you have a javascript problem

1. try a different browser
(2. try a clean install)
3. try to disable modules

I uninstalled quicktabs, then viewed my custom theme in firefox, looked fine
Then viewed it in ie and got that jquery error, so switched to garland theme and error was gone.

Then reinstalled quicktabs but still don't see these extra options, using garland theme.
Can view my quicktab in firefox no errors, but using ie gives that jquery error again.

switched to garland theme and error was gone

vs

still don't see these extra options, using garland theme

this does not make sense, as these are opposite statements..

gives that jquery error

error message?

please try to write clear explanation, something simple like:
garland + IE = ?
garland + FF = ?
yourtheme + IE = ?
yourtheme + FF = ?

Sorry for the hastle, i deleted and reinstalled drupal using fantastico
This has corrected all the errors, even when using my custom theme
It's a pitty it's not easier to find these erros and correct them
But this was the best solution, i hadn't much done anyway
No problems in ie either, so far

Got the same issue with a staging site. Tab content and operation do not appear anywhere. Site has around 60 contrib modules and they are all working well. JS does not seem to be the issue with the site since there are other things running well. I also reinstalled the module twice with no luck. Tested in FF 3.5.4, IE 8, and Chrome with clean cache and no blockers without positive results. Other sites are also using QT without any problems. No sure if there is a conflict with another module or something else.

Your feedback is appreciated.

Thanks,
