conflict with Pagelines

Hi Ricardo,
usually this is related to a conflict with theme functionality.
If your theme use OB functions (https://php.net/manual/en/function.ob-start.php) for html injection Ginger should give problems in page rendering.

If you compare html with and without ginger, maybe you will find some differences in classes on body or some other elements.
Try to check it, if is not an html issue should be a css conflict, more easy to resolve
