In the Admin area of your site, click on “Settings” (on the far right). That should bring up the “General Settings” page.

In the “Membership” row, make sure that the following is checked:
“Anyone can register” (unless you want to manually add users, say friends and family).

And that “Users must be registered and logged in to comment” is unchecked. I think that’s the option that’s blocking the comment form in your case.

If the problem is happening for multiple scripts (including WP’s built-in RSS widgets), and “Connection Refused” is always the problem, then this seems to be an issue with your server’s firewall. Though, it could be with your server’s PHP settings.

Your best bet is to check your webhost’s support area for more info or contact their support.

Have you looked in the Codex?

Read these pages:
The Loop (Take a look at the multiple loop examples)
Pages (Page Templates)

You’ll need to make your own page template for your static front page.

Check your site with the W3 Validator.

Line 262, Column 6: end tag for “div” omitted, but OMITTAG NO was specified.

This looks to be a coding issue. You’ll need to fix the unclosed div and any other issues (though some of the errors look to be caused by a plugin).

Consider using the IE Dev toolbar, and for Firefox, the Web Developer toolbar and Firebug extensions.

Also, your pages have no <title> element.

If this is for Pages (Codex link), you could use what would be a “No Comments” Page Template.

Follow the instructions in the Codex for making a new page template (just copy your theme’s page.php and rename it, add the template name, etc.). Then edit the new template by removing comments related code such as comments_template().

If you’re talking about posts, then that could be a bit more complicated.

steo83, your theme’s code is wrong. It is adding an extra slash (“/”) at the end of the feed link address. From the header.php file:

<a id="i_rss" href="<?php bloginfo('rss2_url'); ?>/">rss</a>

You can either manually fix these links, or choose a different theme. Your theme also has two extra links at the bottom (web hosting and tourism) that I’d remove as well. Take a look at On Sponsored Themes.

Custom fields are designed as variables that can be plugged into a page template and or theme. To use a custom field you will have to manually add the appropriate code to output a field.

One simple function is the_meta. You can add that to your single.php (inside the Loop) with just

<?php the_meta; ?>.

Here’s an example of more complex code:

<?php
if (post_custom('your-custom-field-name')) {
 // if the 'your-custom-field-name' field exists, do this
 echo post_custom('syour-custom-field-name');
 } else {
 // otherwise, do this
 }
?>

You could also take a look at Using Custom Fields in the Codex, but that page seems a bit out of date.

Take a look at this topic: Creating a custom RSS feed.

Just make your own feed template by copying and customizing WP’s default feed templates (there in the wp-includes folder, such as feed-rss2.php). You can use almost any any template tag, e.g. the_tag(). See the Codex: Template Tags.
