Can anyone see if there is a problem with line or does it relate to something else? I've reinstalled Tabber but it doesn't make any difference - it's JQ-TabbedProductDescriptionsV313-1100 in Actinic v11.0.1
I've just been through the laborious job of tracking down the last snapshot that was error-free (9 snapshots ago!), copying all the code and text for the changes I've made since then (I hope!), now I'm restoring everything in the site to bring it back up to date.
This has just shown that the problem is somewhere in my outer layout code which I'm about to troubleshoot. As you say, Norman, your code is fine
I posted recently (last few months) on the Actinic community regarding a single unmatched tag causing similar chaos. Damned if I can find it now after trying searching with lots of likely keywords!
Thanks for the link Norman, I thought that "only happens if an error is made in tweaking" was the most likely cause, but looking at it again this morning I've pinned it down to the fact that the slideshow uses JQuery - there's a call for jquery.js in the <head> section - if I break that link then Tabber works OK.
Looks like I've got to look for slideshow software that doesn't use JQuery.
My add-ons only load jQuery if it's not already loaded (in case you have more than 1 such add-on). That way several add-ons share the same jQuery code.
There should be no problem using jQuery for another add-on. However: try putting your add-ons setup code after the Tabber Setup code and also remove any line that loads jQuery from your add-on as it will already be present.
