Since a week, my website has been experiencing major technical issues:
Frontend dysfunction (mobile):
The mobile version displays an upside-down layout.
The menu and search bar are non-functional.
Product pages and other sections show unformatted or non-responsive text.
Backend dysfunction:
When I attempt to edit a product, a blank white page appears, preventing any modification.
I restored the latest website backup, but the problem persists unchanged.
This is significantly disrupting the usability and administration of the site. I urgently need help to identify and resolve the core problem. thank you
