We had a security problem on a test machine and now my DNN site (a bunch of design hours dropped in)... Unfortunately, I have no backup. (of course). As well, I can't say for sure if this error is due to the security problem.

I am getting the message above in the subject.

I also tried to run the latest 5.0 upgrade install on it, seeing if there is something missing... There was some discussions about AutoUpgrade=True and Install = True issue, but I'm not sure if I should try that since there is content in the DB that I don't want to loose.

    <add key="InstallTemplate" value="DotNetNuke.install.config" />
    <add key="AutoUpgrade" value="true" />
    <add key="UseInstallWizard" value="true" />
    <add key="InstallMemberRole" value="true" />
    <add key="ShowMissingKeys" value="false" />
    <add key="EnableWebFarmSupport" value="false" />
    <add key="EnableCachePersistence" value="false" />
    <add key="HostHeader" value="" />

Any susggestions on how to get it back up and operational?

I get the same error:

This site is currently Unavailable

Please check back later

I have no idea why.. Where do I look?  How do you trouble shoot this?  I have already tried clean installs twice.  This is the farthest I've gotten.

this message generally means that your connection string is incorrect - ie it cannot connect to the database.. You have two areas in the web.config to enter the database connection string both must be entered.

If the connection string is ok then check your sql server configuration

I do agree however that the message could be improved.
