Module development and code questions

Hi, So I bought a Restaurant theme and I am trying to add it and before I was getting POST 8888888 bytes exceeds limits so I made a change in the php file(running xampp) and Now I get this error The file could not be saved because it exceeds 2 MB, the maximum allowed size for uploads.

I have a scenario where i have built a customer a D9 Commerce webshop abc.com . The customer also has bought another exisiting webshop/domain def.com which they will close down but keep the domain.
