Whenever I try to add a new block, it always shows up for Webmasters only.
No matter what I try, there seems to be no way to make it display for any other group. Other blocks are fine, but not custom ones.
How can I make blocks that display for groups other than Webmasters?
You need to go to groups>registered users and tick the checkbox for the custom block in question. Repeat this for anonymous users and any other group you may have.
