Hyperlinks still don't work

Thank you Sayful for your previous response. I have updated to the plugin’s new vesion; however, I am still experiencing the same problem. The content disappears when I add a hyperlink.

Below is the test page I have created.

For a visual of what is happening click on the tabs “How do I sign up” and I have created duplicate tabs titled “How do I get started,” one with no links and the second with a hyperlink.

Thanks for your help!
