How to delete a default block...

I assume you're at Administer - Site Building - Blocks. I'll also assume you're using 6.9 if you're "selling" it.

I'll cover the easy first... to drag those, you need to have your mouse right on the little cross at the left of the item. When you've dragged the item to Disabled, you have to click Save Blocks or the change won't stick.

If none of that works, for the Region drop-down for that item, choose "none", and Save Blocks.

If that doesn't work, good luck.

My solution was to open the database, edit the "blocks" table, changing the status value from '0' to '1' on each block I wanted to remove from the list. To find the correct entry, hover over the "configure" link to get the value (like user/2 or user/3) for the "Who's New" or "Who's Online" block. I have not had any problems yet, but please use at your own risk.

Do not forget to match your theme type in the table.

I believe this only hides the link from the admin/blocks page.

I'm trying to figure this out as well.
Does anyone have the answer to this?

This might because the block code was hard coded in the template itself. Try open up the template file to see if you can manually remove it.

You cannot delete default blocks provided by a module or by core. The only blocks that can be deleted from the admin UI are, for the most part, blocks that have been self created.

One would have to hack core to remove default blocks and when core is hacked it's been said, god kills kittens.

Those in this thread who want to manually adjust the weights of the block (in a dropdown)
can disable javascript in your browser. if already in the administer -> blocks ensure you refresh the browser page

disabing javascript with disable the drag and drop feature. you can then enable javascript when you are finished moving your blocks.

In d6 you can remove useless blocks from drag n drop table by using template_preprocess_block_admin_display_form function

For example, place the code into your template.php

function THEMENAME_preprocess_block_admin_display_form (&$vars) {
unset($vars['block_listing']['-1']['system_0']);
}

The code above removing default system block with drupal logo

OR

To remove all disabled blocks do this:

function THEMENAME_preprocess_block_admin_display_form (&$vars) {
unset($vars['block_listing']['-1']);
}

Enable Devel module to browse array available array elements

I was wondering how to do it just like you! Then with some playing around with my site files I figured out how to do it:

1. It is pretty simple just open your site file manager, then go to the folder where your theme is - in my case it was "/htdocs/drupal/sites/all/themes/rootcandy".
2. There you will find a ".info" file, open that file and there you can see regions[block_name]=block_title list where you can delete unused blocks from!

Good Luck !

At first I create some contents that would be created as blocks, but with the time I change the solution to views, so I disable the option from my content type, but now I have a list of the blocks that were created at that time without the Delete option, any ideas to get rid of them?? Thanks in advance.
