I have checked on our demo and it works fine. To resolve this issue, you can try the following solution.

  • Try deactivating ALL plugins temporarily to see if this resolves the problem. If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).

  • If that does not resolve the issue, try switching to the unedited default Theme (such as Twenty Fourteen) for a moment using the WP dashboard to rule out any theme-specific issue. If you don’t have access to your admin area, you can switch to the default theme by renaming your current theme’s folder in wp-content/themes and adding "-old" to the end of the folder name using via FTP or SFTP or whatever file management application your host provides. Alternately, you can remove other themes except the default theme. That will force your site to use it.

Hope this helps!
