I did an upgrade from nopcommerce 1.3 to 1.4 and everything went well but suddenly the website crash. I receive a message "internal error …". I couldn’t log in so I decide to delete the 1.4 version and start over the upgrade procedure and now i get this message: "You already have version '1.40". And I can’t go further because is stops there.
I probably have to delete some meta data somewhere but the question where can I find the version reference?
