Issue Description
When changes are made within Site Template Style → Nestfund → Basic → Contact Info and saved, the entire website header disappears. This includes:
The contact information section
The language switcher
The logo and main menu/navigation bar
After the header disappears, attempting to restore the header by reassigning module positions results in a completely broken layout. The styling is severely messed up, and the original header structure does not return as expected.
Possible Root Causes
Template style override conflict: Changes made may overwrite the header module position assignments.
CSS or layout structure corruption: Saving may reset or remove container classes used by the template.
Missing or disabled modules: Modules assigned to the header positions could be unpublished or detached.
