I have created an account on ERPNext and I am doing my work on the same .Till now I have been able to create customer , invoice ,supplier etc …All worked fine but now when it comes customizing form or adding some new field or column it doesnt work at all ,it gets saved and when I go back to the print and refresh .I dont see any change the form is same as it was before.Has it anything to do with the fact that I have created an account on ERPNext and not on my local server
