[Plugin: Simple Cart & Buy Now] doesn't display buttons

I get the same error but the shortcodes work ok. It also seems to link to Paypal and Google for processing but with errors.

2020media — There was a mistake in the gui editor for inserting shortcodes — it inserted the wrong shortcode. Should be fixed in 1.1.0. In any case, the shortcode should be something like: [scabn name=”Product” price=”9.99″ fshipping=”1.00″ qty_field = “true” b_title=”Add To Cart”] — make sure it starts with “scabn”

hafman — are you using encrypted carts for google / paypal? If so, that can easily be the problem. Can you disable them (just remove the optional settings for encryption in the SCABN settings pages)? The checkout page should say “no encryption”. If that works, that’ll be helpful to know where the problem is. Google Checkout should be fine if it has your merchant key. Sadly, I couldn’t figure out how to implement paypal’s scheme in php, so it uses openssl on the command line and a set of public/private certificates — if you don’t have shell access to openssl or the certs are wrong, that could give you problems.
