I must ask, are you using Zencart 1.5.1 and upgrading from mod version 1.4.x ??
If so, did you run the installation script "admin/stock_by_attr_install.php", (and test on a test site first?).
Are you using mod version 1.5.3, you may need to follow the small correction here to the install script:

The script adds some configuration settings to the "Configuration -> Stock" page in admin.
See instructions "Instructions/htm/notes.html" for some additional notes.
