The first site was installed XOOPS version 2.0.16, so the new one is exactly the same. I do not really understand what you mean by "2.0.14 (upwards) overriding", but since it is working on one site, i think it should on the other.
When I look at the source of the pages, i see at both sites:

For the templates: I have downloaded the default template from the first site (on general settings from admin section), and uploaded it on the second, and gave it another name (default copy). Then also on general settings in admin config I selected to use the default copy. I think this is the right way to check if this problem is within the template?
I also tried enabling an option called "Check templates for modifications ?" on general settings from admin section.
For the themes: I have re-copied the entire themes folder.
