For error 1, was that on a development machine running in the VS dbugger or was that just using the release files on a server? Would like to have seen the full error message.

For 2 I can only guess that something unusual happened during installation or that you didn't copy up all the files.

For the first site created in the db, the IsServerAdminSite field is set to true or 1 (in mp_Sites table)

When you visit the /Setup/Default.aspx page all available features are installed in sites where IsServerAdmin is true. Other child sites have to have the features added from site settings in the ServerAdmin site by chossing the site from the dropdown list.

So if this is a single site installation and you're not seeing all the features then.

1. check the row for thsi site in mp_Sites table and set IsServerAdmin = 1 if it is currently 0.

2. look in the /Setup/applications/mojoportal-core/FeatureDefinitions folder, there should be a config file there for each feature so check if some did not get uploaded to your server.

After making the change to the mp_Sites table and/or restoring missing files, visit the /Setup/Default.aspx page again and it will re-configure the features for you.

On hosted environments with Medium Trust, see information here. However, neither problem that you mentioned sounds like a medium trust issue.

Hope it helps,

Joe
