Post installation

I have created content and it you go to the front page but it does not show unless the user is logged in. Any ideas on why?

The content for forum topics, recent blog posts, are not appearing unless the user is logged in. The block itself shows but the lists within are missing. The block are enabled as normal without any custom paths or settings.

I checked my logs today and had a nice 13 pages of the same error. It was generated by a quite a few different pages on my site.

i installed drupal 4.5.0 and filestore2.module. but when i enter node/add/filestore2 page i received

Fatal error: Call to undefined function: fscache_is_file_stored() in /var/www/vhosts/drupal/modules/filestore2/filestore2.module on line 332

do you any ideas about the problem? thank you so much.

After installing 4.5, I cannot figure out how to let users edit other user's book pages. I was able to do this in 4.4 just by enabling the "maintain books" permission for all users. What else do I need to do in 4.5 in order to make this work?

I want to change my Navigation menu block, but I don't know how to do it. Right now Navigation has "home" and "search". I want to possibly change the name "Navigation" to something else, and I want to add more links in that section.

I have tried looking on this site for relevant info, but I'm just not seeing it. I would appreciate help, even pointing to some documentation that describes what I'm trying to do.
Thanks.
