I had problem connecting to DotNet Portal and I read all the post that seemed to relate to my problem. I followed up with re-installation of Portal and keep getting the following errors.

Error Installing DotNetNuke

Current Assembly Version: 04.03.01

ERROR: Could not connect to database specified in connectionString for SqlDataProvider

After refreshing,the following error comes up.

DotNetNuke Upgrade Error

The Assembly Version ( [ASSEMBLYVERSION] ) does not match the Database Version ( [DATABASEVERSION] )

ERROR: Could not connect to database.

Login failed for user 'DotNetPanelPortal'.

 I have even done a fresh install and I am still stuck here. Any help will be appreciated,

Take a look at these posts:

Feodor,

Before I posted to the forum, I had gone through http://forum.dotnetpanel.com/forums/thread/401.aspx  and the second item http://forum.dotnetpanel.com/forums/thread/1374.aspx  does not seem to relate to any of the errors. It was after not being able to resolve the issues from previous posts on forum that I decided to do a fresh install.

Unfortunately, with the fresh installation, the issues still remain.

Btw, recently we've found a bug in DNP Installer regarding database user passwords. If database password contains non-XML friendly symbols (like &, %, etc.) that should be escaped then the final connection string will have wrong password.

Try to use for database user the password containing letters and numbers only.
