Hi Patrick,

that's definitely puzzling, and if it's only happening when a Chameleon rule is published then it looks like it's Chameleon-related and some very complex interactions are going on.

Can you please tell me:

1 - Chameleon version
2 - Joomla version
3 - does the template have any HTML overrides in it that might have an effect on this?

Also I wonder about the setting of the active menu item in your Succeed action. If you don't set anything in that drop down, then do you still get the problem? That setting should only have some effect when you are going to the "default page" of your site, i.e. www.example.com/ with no page specified. So you should be able to test if this has something to do with the appearance of the article title, by going to a page on your site other than the default page, and removing the item from the drop-down in the Succeed action.

I hope that helps to narrow the search down a bit.

Best regards,
Stephen
