That removes the categories tab from everyone, including admins. At least it doesn't throw an error.
Let me try this again. I missed a bit of your code, so I just pasted in the whole thing. Now it behaves correctly, but is throwing the following errors (which are appearing on every page):
---
Message: Undefined property: CI::$current_user
Filename: libraries/Module.php
Line Number: 137
---
AND
---
Message: Trying to get property of non-object
Filename: blog/details.php
Line Number: 78
---
the details.php array is somehow referenced by Module.php, I guess.
