Rapidcart Pro SmartPreview problem [SOLVED]

Thanks for you time.
Could anyone help me?
Working with Rapidcart Pro 4 in demo mode (RW6, Yosemite).
Smart Preview doesn´t show me the store page. I am stuck and I have´t had any answer from Foreground support yet. Should be an easy question but… I believe I have more chance to get an answer here.
Thanks for your patience.
It gives me this error:

Roberto from Foreground has solved the problem in a simple sentence.
In case it could help anybody else: Please make sure no text (even blank chars like spaces) are in Settings > Code > Prefix window of your RapidWeaver project.
Thanks!!! SOLVED

I have a similar problem.

I’m attempting to produce an e-commerce website to sell prints etc of my wife’s original watercolour paintings.

I am using RapidWeaver 7 with Mac Sierra OS v 10.12.6. Originally I used Cartloom for the products until they ditched their Free version (I’m a retired graphic designer and the selling of watercolour prints by my wife is not a high flying business and we couldn’t justify the monthly fee for Cartloom on a project with no idea of how it might turn out).

I’ve now switched to RapidCart Pro 4 Starter with Rapid Cart Stacks using the Foundation theme. I am at the stage where I want to preview it before progressing any further.

The RapidCart Pro 4 Manual states:

“ ! RapidWeaver™ 7 supports offline PHP preview, so SmartPreview is no longer needed. This means built-in RapidWeaver™ 7 preview just works when previewing RapidCart Pro pages. Woohoo!”

It doesn’t work for me. Even RapidCart’s own Demo site, included in the download, won’t preview the RCP stacks.

I’ve searched all the forums and posted my question to Foreground but so far haven’t found a solution. Hopefully there’s a simple answer to my problem.
