For some reason, when testing my module (displays a form), the module seems to "disable" itself. I reload the page, and the block isn't displayed anymore. If I go in the "Module" menu, my module is there, but unchecked.
I unfortunately do not have a pattern to reproduce what makes this happen. The website is local online for testing purpose, so no-one can tamper with it.
What could be causing this problem, and how can I find the cause?
EDIT : Here's the module.info :
name = "Module title"
description = "Module description"
package = Companyname
core = 7.x
version = 0.0.1
configure = admin/config/system/mymodule
