Post installation

I've just installed Drupal 4.7.3 on my host. I've also installed PHPTal theme engine and PHPTAL library via PEAR. But now when I try to use tal themes i get the white screen with an embedded comment that sais:

PHPTemplate was instructed to override the page theme function, but no valid template file was found.

I've poked around php code for both, but since I don't know Drupal's API i'm totally stuck.

Help much appreciated.

So, I just installed the newest version of Drupal, starting on a new site, and everything worked fine but I got the message

Access denied for user: '****@*****' to database '***_****' query: LOCK TABLES cache WRITE in /home/*****/public_html/drupal/includes/database.mysql.inc on line 120.

(The *** are just substitutes for the real things, didn't really wanna post it on here)

I have a home link as one of my primary links in the header. Now I want to disable the home link at the top of every page/node. Does anyone know how?

I run a high traffic site, hundreds of nodes, typically several hundred visitors are on at any given time.

My problem is with drupal cache. I can't remember where, but I remember reading that Drupal cache is completely cleared everytime any node is added/edited..etc

This is exactly when my site will hang up. During peak hours, if one of our writers contributes a node, our server will overload and crash.

What are my options? I've heard about file based cache, will this help me enough to fix the problem.

i have installed pdfview module, it requires tcpdf and i fave installed too, the problem is that the module dont funcione

in the modules page in admin, pdfview dont have any description, and when i open a node, where shoul put "view as pdf" put "array", nothing

what is the problem?

Is it possible to create a page that shows all of the comments neatly formatted? :)

Thanks,
Allen
