How can it be that I followed the instructions exactly as written, TWICE, and still don't have tabs? All I get is a regular unordered list. I even reverted the relevant templates to the defaults before starting, just to be sure it worked.
Edit: Found the solution. I had applied Schnee's fix above, but not to this part of the code:
Code:
<!-- Tabbed Forum Home Header Code -->
<link rel="stylesheet" type="text/css" href="/clientscript/tabs/ajaxtabs.css" />
<script type="text/javascript" src="/clientscript/tabs/ajaxtabs.js"> </script>
<!-- /Tabbed Forum Home Header Code -->
Once I did that, it worked fine. Perhaps this should be in the installation instructions?
