I have just purchased the upgrade. Following instructions for upgrading, I removed the old free version of the plugin and installed the new one from the zip folder I had downloaded. I activated the plugin using the code I received via email. But the plugin is now not working anymore. When I click on one of my accordions I had previoulsy created with the free version, I cannot change anymore to the "content" tab or any other tab. Just nothing happens when I try to click on them. Also on the websites where I had embedded the accordions, they are now unfolded and don't fold again when I click on them. Any help appreciated to fix this issue. I received version 3.1.20 for download.

Please check if you have installed any cache plugin. try with deactivate cache plugin or debug your admin dashboard or accordion page for jQuery error.
