Drupal 6.x

I'm playing around with a new site on Drupal 6 and have the following code in the view hook function of a module I'm building:

...
$slide_data = array(
'title' => t($node->title),
'no_of_rows' => $no_of_rows,
'rows' => $rows,
);

$node->content['myfield'] = array(
'#value' => theme('istv_slidepreview', $slide_data),
'#weight' => 1,
);

function theme_istv_slidepreview($slide_data) {
...
}

I installed Drupal 6.0 manually yesterday (my host is Powweb). I had a couple of things, but I was able to work through them and get the install completed. Once it was done and I went to my site, I just got a blank page. No errors, nothing. If I went to the site like this - www.mysite.com/index.php I was able to get to the "Welcome to your Drupal website" screen. If I clicked on any links on this page, I get a white screen.

This morning, in continuing to figure out what is going on, I found the topics relating to the memory size in the settings.php. I've added that and I still have the problem. I was also trying accessing the site by different browsers. On one of these, it wanted to download a file. Hoping that it would help I did and below is the text from that...

I've noticed that Google and Yahoo! can search the content of .pdf files. When I do an internal search on my Drupal site, which has PDF documents as attachments, the content of the PDF documents do not show up using the Drupal search module.

Does anyone know if there's a module that will enable PDF search on Drupal?

I have installed drupal 6 and the settings tab for comments disappeared!
Where is it located now?
It used to be "http://www.domain.com/admin/content/comment/settings" and where is now?

Hi all,

First of great software you have there with Drupal, i am very impressed by it. :o)

But i have a little problem when i upload a theme in Drupal 6, i upload it to /drupal/sites/all/themes/"themefolder"/
as it says in the handbook, but even that its chmod right and all, i cant find the theme anywhere in the control panel....?
I can only see the default themes...
Does anyone know what i am doing wrong here?

I have a new clean installation of drupal 6.
When i wanted to change the color scheme in garland the only one that works is the defalt. If i try do use some of the provided it seems like there isnt any css at all loaded...
Resulting in a very very ugly site... but no error messages
