Hi All,

I took over a project which involves LAMP, Drupal6 and Python.

So far I've done programming mostly in PHP or Python without understanding exactly how Drupal works. Everything was going OK but now the application is behaving very weird, there are some system changes that I'm sure I didn't do (at least directly) and no one else.

So at this point I really need to understand how Drupal works (high level). I got books from library but honestly Drupal seems too complicated to me.

Is there any source I can use to learn Drupal mostly at system level? I will pay.

Best, Katy
