I've installed the extension by transferring all of the "Upload" folder to my opencart FTP, but the only folder included in the downloaded file was vqmod - the settings.xml page has been transferred into my main VQmod page, but the extension does not appear to be listed on the extension list... help?
Yes, the only file is owc_store_company_settings.xml. When installed, you can goto your store system -> Settings page and you will see on the store tab extra company settings from my extention. So its is not a module.
Which version of OpenCart do you use. The extension supports OpenCart version 126.96.36.199 and above.
