I am using JCH to optimize the speed of the my website.
When JCH is enabled, and when I call Accordions in a module that is available only on certain pages, it is not working. The text is correctly display but there is no + to expand the content of Accordions.
Looks like JCH is causing the issues.
You could try a different optimization method in JCH. Or exclude the Tabs & Accordions scripts and styles from JCH.
For more help on JCH, you should ask them.
Why it does not work well when it is used in a module affected on certain pages? The module is not called by a loadposition but loaded when the page is.
