Drupal 7.x

Had the error below whenever I clicked UPLOAD to add an image to an article, so I completely removed D7.10, created a new database, and did a reinstall. The only module I added was ckeditor 7.x-1.6. The error is still there with the fresh install. The popup reads

An error occurred while attempting to process /star-watcher/drupal-7.10/file/ajax/field_image/und/0/form-P3VEa4NTzxFxkNBYQaoC5Y8XY8OsK79LLD4svpvKcg: Access is denied.

I have been trying place a chat on my site, http://www.cigardiary.com, where groups of cigar smokers can gather to chat. There were a number of modules dedicated to chat. One of them, PJIRC looked promising, but the client threw a security violation when starting up, and I didn't want to subject my folks to clicking off a security violation each and every time they fired up the client.

Then I found LightIRC.com who produced a Flash chat client that was pre-integrated into their irc.lightirc.com server. I was thinking that I would need to write a module to do it, but then I got another idea.

Step 1: Create a custom node type.

I created a node type called LightIRC Chat. This allows you to create a custom node template that only applies to the chat node type.

Step 2: Create your custom node template.

My template is called node--lightirc_chat.tpl.php and contains the following code:

Hello people.
I have a problem i hope you can help me with.

I have been making a website with wamp local server, that means with no password and root as user name when i installed the site.

Now i want to, upload it to my web server.
First af all, i exported the database from the local phpmyadmin as a sql. file.
And i did import that to my webserver.

Then i use my ftp program, to transfer the directory of my localsite, to the directory at my webhost.

I've been searching for days and although this question has been raised I haven't found any answer how to do it in drupal 7. So if you could help me I would be most grateful.
I have two content types, class and teacher.
A user can add a teacher.
And a user can add a class.
Within the 'class' form I have a field 'current teacher' and other fields from the content type 'teacher'.

I know I'm not really an idiot, but trying to use Drupel is making me feel like one! Is there no place to get instructions on how to use this? The help included with Drupel is anything but, the forum entries are all Greek to me. I have some programming in my past, and web dev for several years, but I guess at the age of 50 I need some clearer instructions than my younger colleagues. I need something in plain English, that explains step-by-step how to get content to show up on the pages I intended it to be on! Nodes, blocks, panels, etc. mean little to nothing.

I know about form builder, but that's not quite ready for prime time.
