Hello,
That does sound strange.
First, can you make sure you’re using the latest version of Integral Lite?
That would be version 1.4.8.
Second, it could be a 3rd party plugin causing some sort of conflict. Try disabling all plugins, except those required by the theme, and see when the problem disappears. Then you will have identified the problematic plugin.
Lastly, if none of those options work, please provide me with admin access to your site so I can log in and have a look. Make sure to select Set as private reply when responding.
