On the home page for Jlinked in the 3rd Party integrations area is lists ZOO as one of the Joomla components Jlinked integrates with. So far I can't get any Apply button to show up in ZOO items. I've tried a Text Area with Jlinked code, I've tried loading a Jlinked module into a ZOO item text area and I've tried a ZOO Joomla module. The area shows up in the ZOO item where the Apply Button should be but the area is blank?
Is there a special ZOO plugin needed? Is there another way to integrate this?
That will work for both the www and non-www version of your site.
If that doesn't help, please let me know a URL where you've implemented the LinkedIn widgets so we can see what's happening. Usually, when we see a page, we can diagnose the problem pretty quickly.
