Blog Error Fix

I am installing an open source blog (from b2evolution) on my website. Although I have my posts entered and the layout pretty much set, it is throwing some server errors that I need fixed.<br><br> You can see the blog here:<br><br> [login to view URL]<br><br> Problems to be fixed:<br> 1) when you click on a blog entry, it gives an error<br> 2) I don't want the entire blog posts to show on each page. I want the beginnings of the post to show, with a "read more" link, which would then go to the full blog.<br> 3) I need to get rid of the links to b2evolution on the side and the bottom<br> 4) I would like for users to be able to browse archives by date, and have that option available on the right menu bar.<br> 5) I would like to attach the site to an existing rss feed (I can provide the feed info).<br><br> I need this done asap. Thank you.
