hi,
after adding the files of the discount codes module, i went to admin -> modules -> order total (like it says) to install the module.
I clicked "Install Module" and found that it was already installed with a sort order of 4.
I was confused so clicked on it and it showed no options.
So i decided to remove all my other modules. after doing that i found out that:
a) the discount codes module was still installed but not appearing in the installed modules menu
b) the total module had disappeared from admin (though all the files are still on the server)
c ) i cannot edit, install, save, remove etc. other modules.
what has gone wrong????
