Have you tried to deactivate all plugins and use the default WordPress theme?
No I have not deactivated all plugins and used the default WordPress theme. I need to have the plugins and the theme I have.
You should deactivate it one by one and check the issue after each plugin deactivation, and you’ll find the plugin which cause this problem. If all plugins are good, then the reason is your current theme.
