Hello Dien,
I’m sorry you are having this issue. Let me help you out here.
Based on your system information I see that you are using older versions of our plugins. I would recommend you to update to the latest versions. Also check your other plugins and your theme if they have an update. A lot of bugs are being fixed with every release, and we usually support only the last version of our plugins.
If you are still experiencing the issue after the update, then please switch your theme to a default one like twentysixteen. Check if the issue still exists and let me know the result.
If the issue still exists with a default theme, then I would like to ask you to run a test for conflicting plugins based on this handy guide here:
Testing Conflicts With Themes and Other Plugins
Let me know how that works out and we take it from there.
Thanks and cheers,
Andras
