I downloaded nopcommerce tool in latest version and edited it and after that I published this project on smareterasp.net but when I install it it shows this error and I can't solve it Setup Failed: Sequence contains more than one element I do not have the time. Please Help. Thank you.
This exception is typically caused by trying to install to a database that has already been installed (i.e. already has tables). To use an existing database, you need to copy the files in the App_Data folder before you start the application. appsettings.json plugins.json
