Deprecated - Usability feedback

Im running Drupal 5.7 with jsquery update and tinymce

I was getting the white screen of death on the user edit page with a message in the top left of the page saying disable rich text
I have tinymce set up so i can disable it on the page, this seems to cause a problem on the user edit page

This bug only seems to happen in Firefox, it doesnt occur with Safari

Heres how to fix the problem

Go to admin Tinymce and click to edit your tinymce profile

Under the visibility field set you should see Tinymce is set to be displayed in these places

I installed the module Autologout 6.x-1.5 [Adds automated timed logout]. And it would not logout. Do I miss something?

The Site configutaion:

Enabled module [box checked]

Timeout value in seconds: 600.
The length of inactivity time, in seconds, before auto logout

Checked -> Enable watchdog auto-logout logging

authenticated user: Enforce
Administrator: Enforce

The permission settings: All user can access Autologout.

I have to admit I am a total newbie to drupal and know nothing about PHP
I have looked and looked for a way to sum 'Intergers' from a Content Type I have created upon submission and can not find any PHP Snipppets on how to do this. I know this is so simple but I am struggling with Syntax on how to do this. I have looked all over the site for a way to do this. If anyone know how or has some basic Snippets I am sure I can learn and run with it
Thanks if you can help

I get the error message "The directory files/images is not writable" as soon as I try to create any kind of content, including comments, books, pro-con arguments etc
When I use the same database on my local computer, I do not have this problem,
I did not have it some days ago, and I did not change anything on my server.
What can I do?

I logged in as administrator. I made the site off-line under site maintainance and logged out. Now i am not able to enter the site. It gives the message site offline. what should i do? Please can any body clarify.

thanks
