You can not have a theme with the same name as a module. Doing so will create errors such as: warning: include_once(sites/all/themes/[themedir]/[modulename].admin.inc) [function.include-once]: failed to open stream: No such file or directory ... on line 283. and warning: Missing argument 2 for [modulename]_help() in C:\Users\owner\Workspace\simplenews\sites\all\modules\[modulename]\simplenews.module on line 2164.
