I managed to find a lead by noticing errors in firebug console window:
TypeError: b.browser is undefined
<code>...se,B=b.extend(b("<div/>")[0],</code>{prop:0}),M=b.browser.msie&&b.browser.version<7&&!w...
jquery....r=1.3.4 (line 18, col 207)
TypeError: jQuery(...).fancybox is not a function
jQuery("a.fancybox").fancybox({
Search on web showed that this could be due to including older version of JQuery. But none of suggested solutions helps.
Any suggestion how to figure out what is causing these errors?
