Missing order total modules

[RodG]

I don't know if this will be of any help, but there should be two files for each of the installed modules.

The 'main' files (that hold all the code) should be found as
/includes/modules/order_total/ot_moduleName.php

The matching language files for these should be found as
/includes/languages/english/modules/order_total/ot_moduleName.php (typical installation)

Also, check (from the store admin) - modules->order_totals. Do they appear there? Are they enabled? Is the sort order correct for your environment?

Cheers
