Post installation

Hey, folks. The site I'm working on right now is designed to emulate an FTP browser, and I'm using Flexinode (hail Flexinode!) to create the file nodes. When you click preview on a file upload, it doesn't upload anything, and it wipes the information in the fields (!).

I understand the reasoning behind why it does that, but given that this site is designed to be as stripped-down and user-friendly as possible, I'd rather not have this functionality to confuse my tech-noob users.

So I made a custom error 404 Page (page cannot be found) > enter its URL into administer > settings > error handling in the 404 section > then enter a bogus URL like http://localhost/practice/jfdsfjsdklfjsdklfjdsfklsdhn to test it > my custom error 404 page is not returned. Instead, I get list item content from my home page that has a View applied to it. This is really strange.

This is really odd.

This morning I noticed that Google was running into some "Access Denied" pages on my site. No problem, right? Some of the pages are protected from anonomous access. But then I dug deeper and noticed some of the public nodes were returning the "Access Denied" message.

What's worse is when I tried to hit the nodes as user 1, I got "Access Denied"

Oy!

The first thing I did was access the database directly to make sure the node in question existed. Yep.

I'm new to Drupal and I'm embarassed to write this, but I have set my site to Off-line status while I'm working on it and I can't figure out how to log back in as administrator. Please help. I am, apparently, an idiot.

Just as the title says, let's say the user is looking at an article. What is the php code to tell if the user authored that article?

I'm trying to set up block visibility to roles for some of my blocks and am *very* frustrated at this point. I choose Show if the following PHP code returns TRUE (PHP-mode, experts only). Then enter my code...and it is completely ignored. I've even tried just entering

return FALSE;

Which should never show the block, but it still shows up on every page.

ideas?
