A. The Hosted Ecommerce Service has two layers of files as noted below:
Customer End Storefront and Admin component.
Shared Core Library Files which are shared by all Hosted Ecommerce Stores on server.
The shared core library files are maintained (upgraded/patched/security updates) by us so that you do not have to bother about patching files. Instead you concentrate on running your business. We always stand behind your store as far as security and features enhancements are concerned.
