Post installation

I don't know what I did wrong, but enabling XTemplate always gives this sequence of errors. It is impossible to log on to the website when this happens, so I have to go directly into the system table and set the status of xtemplate to 0, before it works.

Below is the type of error I get and it appears to be generated for every node type.

In case it may be relevant, my installation was an upgraded one, not built from scratch

The default email sent to newly registered users inludes a paragraph about logging in to other sites.
I didn't want that so I commented it out - but I realise I'm not supposed to alter the files in Drupal.

/* \n\nYour new %site membership also enables to you to login to other Drupal powered websites (e.g. http://www.drop.org/) without registering. Just use the following Drupal ID and password:\n\nDrupal ID: %username@%uri_brief\npassword: %password

I installed the image module and am very happy with it- good job developers!

I tend to remove stale galleries on my site though and I see no easy way to accomplish the removal of content.

You can delete the taxonomy term for the specific gallery and when you delete an image node it is supposed to delete the associated images and thumbs. Is there a way to mass delete the image nodes?

You could remove the node records from MySQL and delete the pics but that seems clunky.

php and mysql are working fine. (tested for user id pword connectivity)
The "front page" of drupal works fine. Running clean_url.
However, when going to a node the error (from the log) occurs:
File does not exist: /usr/local/etc/httpd/htdocs/drupal/node/view/7
/usr/local/etc/httpd/htdocs/includes/database.mysql.inc on line 12.
I did some tweaking to httpd.conf prior to this problem being discovered in the

allowoveride none

but have restored it to the above.
This is a production site. Please, help if you have the time.

I'm wanting an index by node type similar to the taxonomy_dhtml or taxonomy_html overview page. So instead of displaying my taxonomy it would display nodes segregated according to book, forum, story, static, etc.

I'm also wanting to include /book/ on my home page. Notice, I do not want to change the home page to /book/ -- I still want a cascading list of the most recent posts. But I'm wanting the contents of the /book/ node and perhaps the /story/ node to appear on the home page as static sections.

After populating the drupal mysql database with my membership list, I recently noted problems with the addition of new users. This is the error that appears:
user error: Duplicate entry '22' for key 1
