[Solved] leaving a comment

@wgwt,

This kind of issue is usually caused by either conflict with other plugins or the active theme.

Please deactivate the plugins/theme one by one and check after each deactivation to find the problem maker.

Please let us know which plugin/theme causes the issue. 

Keep the cache plugin (if you have) deactivated during this testing process.

Don't forget to press Ctrl+F5(twice) on the frontend each time before checking.

@wgwt,

We don't find such an issue on our test websites. Could you please send the admin login details to info[at]gvectors.com email address? I'll ask the developers to check the issue for you.

Alos confirm us to deactivate some plugins if it's necessary.
