The Problem is with a new Drupal installation, and it's not on a VPS1

1. Is anything other than SuPHP being used? If so, recommend SuPHP be used & check permissions.
   
2. Is the server using lots of RAM, having MySQL issues, or experiencing high load post-install?
   
   1. If yes, the PHP and MySQL settings are likely set too conservatively for Drupal to work properly
      

It's an existing site

1. Are they on a VPS1 or have they upgraded servers recently? If they've migrated/upgraded, check the PHP version.
   
2. Is anything other than SuPHP being used? If so, recommend SuPHP be used & check permissions.
   
3. Is this a new Drupal install? If so, and it isn't working, make sure it was installed properly via cPanel/Fantastico.

Site configuration in Drupal 6

Go to Site Configuration (Administer > Site Configuration). Most options here are pretty self explanatory, but a few important ones to consider are:

   * Error reporting
     By default all errors are output to the log and screen. When your site is ready for production you should change this to just write errors to the log only.
   * Input formats
     Input formats are incredibly powerful and often missed configuration step early on. The default for most user accounts is Filtered HTML.
     This is a list of tags allowed by normal users to use on your site. There is a very minimal default selection which you can change.
   * Performance
     During development, caching should be disabled (default). Once the site is ready for production you should set caching to normal.
     Experiment with these settings to find what works best for your site.
   * Site information
     In addition to Site name, which was set during install, you can also add a slogan, mission, and footer. Other options include setting
     a name for anonymous users and changing the default front page setting.
   * Site maintenance
     If you need to take your site offline for any reason, here you can do this and set a message as well. It is useful to know how to log
     in once you have turned your site off-line for maintenance.

File Structure

While all PHP-based CMS-packages perform what can basically be considered the same task, differences in functionality and scalability arise out of how those tasks are performed. Drupal File Structure

Versions & Upgrading

http://drupal.org/documentation/upgrade/6/7 A number of customers are anticipating the release of Drupal 7; many are likely to want to upgrade.

Upgrading your Drupal installation

The process of upgrading to the latest version of Drupal can vary in difficulty depending on the complexity of your current installation. You can only upgrade from one version to the next version. For example you are trying to move from Drupal 5 to Drupal 7 you first need to upgrade to Drupal 6 before you upgrade to Drupal 7.

Backup Your Current Site

It is always highly recommended to backup your site before any update or upgrade.
A full backup consists of making copies of:

   * all core Drupal files and folders
   * all contributed module files and folders
   * all contributed theme files and folders
   * all other files and assets that have been uploaded via your Drupal site (e.g. /files folder)
   * the Drupal database

For more information about backing up your Drupal site see http://drupal.org/node/22281

Update Your Site to the Latest Stable Release of Drupal 6.x

It is important for your current site to be updated to the latest stable release of Drupal 6.x prior to upgrade because point releases sometimes introduce
minor database schema changes. These changes will be expected to be in place by Drupal 7 when you upgrade.
For detailed information about updating your Drupal 6.x site see http://drupal.org/node/390448

Update Contributed Modules as Required

As part of the upgrade planning process you will have researched whether modules currently installed on your site will be available for Drupal 7.x.
Each module will have a slightly different upgrade path to a corresponding Drupal 7 version. In many cases you will be required to update the modules
on your site to their latest versions for Drupal 6.

Visit the project page for each of module installed on your site for instructions on how to update to the latest version. If you have the Update Status
module installed, it will provide you with links to the project page of each of your installed modules and can help you identify whether you have
completed all the required updates.
