After we moved the server from the US to UK we are facing this issue.
The problem: Configurable Products(attributes >4) can't be saved or edited when working from India.
When we click 'Products > Catalog > Configurable Products' - then we load a product with >= 4 attributes the entire admin becomes slow and the products are not saved but when we login into the admin section from the UK, we were able to add items under configurable products.
How is this possible and what should we do?
Also, for 'Customizable Options', I don't see the title(screenshot attached).
