Hello
Sounds like it might be better for you to use the base area of your template instead (base-1a, etc.) as it would have the necessary module positions. For this area of your template to display a full width background we would have to make a few amendments to your template. May I suggest sending temporary administration access to your Joomla installation to
[email protected] and we will make these changes for you. For our reference please paste a link to this post in your email.
