I'm having issues with a block that is created with a module I wrote. This module works on 2 out of 3 sites, all of which have a similar setup, so I'm not sure why it's being picky on one site. Here is what I know:

  1. The block is not showing up in the list on admin/structure/blocks, and is not available anywhere else.
  2. hook_block_info() is being invoked on the site, but none of the other functions are being called. On the other two sites, calls are made to all the functions.
  3. There aren't any blocks in the blocks table with the same name, but there is a record of the block in the table for each active theme.
  4. I tried deleting these records out of the blocks table with no luck.
  5. I've tried clearing cache and uninstalling/reinstalling with no luck.

Here code for my .module file. It is available here as well: http://pastebin.com/EYFgneie

I've exhausted all of my knowledge, so I'm up for any and all suggestions. Thanks in advance for you help!

  • Has the module name remained consistent? Make sure it matches what you are putting as the prefix before your hooks. That's gotten me a few times. Also, see if commenting out the "Only show this block on non-admin pages" condition makes it show up. – jazzdrive3 Aug 23 '13 at 19:46
  • Thanks for the suggestion, but I'm still having no luck. I don't think it has anything to do with my module, but rather something on the site. Also, the only function being called is kcc_menu_block_info(), whereas on the other sites they all get called. – richard Aug 26 '13 at 17:01

I have no clue why, but having this in hook_block_info() is causing my problem:

'status' => 1, 

That is supposed to set the block to be enabled by default, but for some reason it removes the block from /admin/structure/block for all three sites.

This solved my problem, but it doesn't seem right. Any thoughts?
