The accordion shows up (embedded in an article), but the tabs do not open. This is true for either click or hover.
It worked before and now it doesn't.
The installed version is 3.0.0
I bought the extension again, as it showed that there is a version 3.1.0
The download link gave me the 3.0.0 version again - reinstalling didn't solve problem.
Any ideas? Thanks in advance...
