Sorry you didn't say that you are installing on arvixe... as I post to other topics just get out from arvixe... because their servers is overloaded they have to much customers and to much connection to sql server "they told this for me when I had the same problems as you"
Error is "Invalid column name UniqueSeoCode". And it means that "statcom" did not execute the upgrade script over his database. Doing it will solve the issue. Arvixe is very good hosting company. If user didn't properly deploy the application, it doesn't mean that Arvixe is a bad company
