The "responsive classic" template is designed for ZC v1.5.5, and is NOT compatible with ZC v1.5.4.
There ARE numerous other template addons for v1.5.4 which are responsive.
If you are using v1.5.4 then your ongoing problems should be discussed in a separate new discussion thread, not in this one about Responsive Classic in v1.5.5.
I suspect your problems are a result of a bad install. Perhaps you should ask GoDaddy to upgrade their Zen Cart install to a modern version.
