Hi,
I installed nopcommerce via WebPI a few years ago. So I do not have the source codes.
It had been published and was working fine until recently. The site is no longer displayed. This is not a problem with DNS or network (verified).
I have no error message. The site is still there, the database also, and so on.
I do not know the exact version installed ... (3.6 I think)
To upgrade to version 3.8:
1. I made a backup of the database.
2. I ran the upgrade script
3. I downloaded the sources of nopcommerce 3.8 and I opened the solution in Visual Studio
I executed. The installation page is displayed. I enter my connection string. Result: Invalid column name 'LeasedByMachineName', 'LeasedUntilUtc'. Solutioned with post: https://www.nopcommerce.com/boards/t/40359/invalid-column-name-leasedbymachinenamerninvalid-column-name-leaseduntilutc-error-while-upgrading-from-36-tp-37.aspx
I has made the same by downloading nopcommerce 3.6. In both cases:
Invalid column name 'XXXX' for : CompanyName, CompanyAddress, CompanyPhoneNumber, CompanyVAT
How could I do it to get it back? Or how I could recover the data from my database to inject them into a new database of a new nopcommerce application?
Knowing that I do not have access to the administration and that I can not export in XML ...
Best regards, Andrés
