I'm developing a website with some modules that I created and I have the following problem:
When updating Drupal core, one of the modules I created is disabled and I don't know why, the module's structure is like the other modules that I created but no one of the other modules is disabled.
Below is the mymodule.info file

; $Id: market_info.info$
name = "Market Information"
description = "Create blocks of market information."
; Information added by Ashraf Sufian on 2009-02-25
version = "6.x"
core = "6.x"
project = "market_info"
