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:
- The block is not showing up in the list on admin/structure/blocks, and is not available anywhere else.
- 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.
- There aren't any blocks in the
blockstable with the same name, but there is a record of the block in the table for each active theme. - I tried deleting these records out of the
blockstable with no luck. - 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!
