When I update the Atalhualpa theme, I understand that I need to also update the content of any folders within the themes, such as the header images.

In my experience, all the other settings (background colors, etc) remain intact, as they are in the database.

However, I have just added some code to ADD HTML/CSS in the options.
Can you confirm that this information too is in the database? Or will I need to re-enter it?

Thanks,

anything you add via the options is stored in the database so yes the Add HTML/CSS info will remain
