Hello!
I'm trying to upgrade from version 3.40 to 3.90.
I updated the database, in order of time, of all versions (from 3.5 to 3.90).
Then I deleted all the files from 3.40 and inserted those of 3.90.
I cleaned up and rebuilt the compilation.
When I test through Visual Studio on my browser, I get this error:
"
System.Data.Entity.Core.EntityCommandExecutionException: 'An error occurred while executing the command definition. See the inner exception for details.'
Internal exception
SqlException: The column name 'RoundingTypeId' is not valid.
"
The page is: CurrencyService.cs in /Libraries/Nop.Services/Directory/
What can I do?
Thanks in advance
