We have the SandBox Developers username, password and Signature saved.
We also have the PayPal mode selected as SandBox, but we still can't get past checkout. "There was a problem connecting to PayPal to setup your purchase. Please try again."
The Store is based in Australia, the PayPal account is a US one and the currency is in Euro. The products are downloadable.
Will any of this cause the SandBox mode to throw a fit?
I know the Live version works fine when the Live API credentials are saved, but for some unknown reason, the SandBox just doesn't seem to want to.
I've deleted, re-installed MarketPress, deactivated other plugins etc but still no luck.
Any help would be appreciated.
