Hi,
Regarding the email probelm see this thread as this issue has come up before but I don't have a solution for it. If you are using the very latest mojoportal code from svn trunk, you can try adding this to Web.config or user.config:
<add key="DisableDotNetOpenMail" value="true" />
to make it use the normal .NET mail classes instead of DotNetOpenMail. I don't know if that will solve it but its worth a try, the setting only exists in the latest code from svn trunk though.
Regarding the forum issue, I was able to produce this probelm on my machine using MySql and configuring a forum for anonymous posting. I have fixed it here so it will be fixed in svn trunk within the next few days. You can fix it in your copy of the source code if you look in mojoPortal.Features.Data.MySql /Forums.DBForums.cs the method ForumThreadGetPostsReverseSorted
look for this:
sqlCommand.Append("COALESCE(up.TotalPosts As PostAuthorTotalPosts, ");
and change it to this:
sqlCommand.Append("COALESCE(up.TotalPosts, 0) As PostAuthorTotalPosts, ");
Please, in the future, post only 1 question per thread and don't start new questions on an existing thread.
Best,
Joe
