CiviCRM Community Forums (archive)

I was working along just fine, importing different kinds of relationship data.
All of a sudden, the tabs at the top of the display of an individual record disappeared.
They were there one minute, gone the next.

If I look at the source I still see:

<div id="mainTabContainer" dojoType="TabContainer" style="width: 100%; height: 600px; overflow-y: auto;" selectedTab="summary">

in the source.

I've tried logging out, closing firefox, rebooting my computer.

However, if I login to IE there the tabs are there.

Looking through the forums a little more I found a thread which solved my problem.

Basically, the problem was that my Resource URLs (found under Administer > Global Settings) were incorrectly set.  Once those were corrected, all the javascript features began working again, including the tabs on Constituent pages.
