Post installation

Hello

I have added the video module. When I upload a video through the module and then go to play the video the site will not load. I cannot load any part of the site. After about five minutes or so I am able to load the site again. When I check the administer page I find this error

The directory /hsphere/local/home/shunshif is not writable, because it does not have the correct permissions set.

the error is right before the log showing that the video node was actually added. I can then play the video node.

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.
