I have a website on 05.05.00 (653) DNN installation, .net 3.5 and sql server 2008 Express which i have moved to another server (.net 3.5, SQl Express 2005)
I have followed this article to convert the database http://www.sqlservermart.com/HowTo/MS... and i've done all the necessary corrections(change to new db name and user) , i have copied all DNN files to the new server, changed the connectionstring (i have some doubts of the correct one although the server address it's been given by the provider), i tried different connection strings, i've read similar to this problem articles but cannot have the site working.
the error i'm getting
Thank you in advance for your help

please check file permissions and make sure, windows user used by ASP.Net as configured in IIS application pool has full permission for all files and subfolders.

Although Sebastian's suggestion to check file permissions for the ASP.Net worker process account (IIS Application Pool Identity Account) is also essential when moving a site to a new hosting provider, it appears from the stack trace that the problem is in not being able to read the connection string from web.config. Maybe an invalid character, mismatched quotes, misplaced comment characters when changing the connection strings (2 - one in <connectionStrings> and the second in <appSettings> sections).
