I have a new website for a client who wanted a shop. We created it in WordPress (WordPress is quite new to us, we are used to websites the old fashioned way). And we set it up fine. They had PayPal.
But have now decided they want Worldpay and having a heck of a time working out HOW to integrate it. There is no clear answer. Would love to hear from anyone else that has done this. Spent ages going round and round with this but can't find the answer.
