When I create a custom block, it does not appear in Blocks Administration in the System module. I can locate and edit the block via the Groups module, but I cannot delete it.

Why does my custom block not appear in Blocks Administration? How can I delete it?

Hello tongo,

If you are using the 2.0.x.x Branch:

have you checked in the, Show blocks visible in, dropdownlist. It starts out showing blocks on the frontpage, then you can check what blocks are assigned to modules by selecting them in the list.

In example, if you created a custom block, filled it with content, and then submited without making it visible, it will show up in the first block list.
But if you made it visible, and set it to show up in, lets say the news module, you must select the news module in the list before you can delete or make any changes to it.

Hope this helps,
Regards,
André Thoresen

Excellent tip. Thank you. The lost blocks have been located.

Yes, I'm using 2.0.x.x. Is there a "show all blocks to the admin regardless of where they're located so he doesn't have to waste so much time searching his own site just to make a two-second change to one stinkin' block" function in other versions?

Another tip for finding lost blocks: Click to get the Groups page. Now use Ctrl+ F to find your block. Click on its ID to open the settings page for that block. Now see which pages it is set visible for. See my TUTORIAL
