Most issues are caused by a conflicting plugin or theme. When diagnosing an issue, first try deactivating all plugins but Panorama. If this fixes the issue you know there is a conflicting plugin. Reactivate each plugin one by one until the problem returns. This will identify which plugin is at fault.
If this doesn’t fix your issue, try switching your theme to Twenty Seventeen. If this fixes the issue you know there is a conflict with your existing theme.
