Can you edit a visualforce page in production environment
Sonam (Salesforce Developers)
If your Visualforce page doesn't need a custom controller, you could be able to create it on production, however, if there is a apex class invloved - you will have to make the changes and deploy on production: https://success.salesforce.com/answers?id=90630000000gnGwAAI

Yes, you can edit a Visualforce page in production. This is not true for classes and triggers. If the page is a part of a managed package, you can only view it.
