This can be caused when there is invalid transaction data sent to PayPal. This CANNOT_BE_ZERO_OR_NEGATIVE error should be unrelated to your browser or account though. Could you please give it a try with a recently updated browser like Chrome or Firefox? Hi found that Safari 11 or older may not work properly with the smart buttons and hosted fields. I tried it with the sandbox info I could find and my merchant id but that didn’t work.Īny help is appreciated.

No where can I find a sandbox merchant id. In dashboard-myapps & credentials-sandbox-default application it lists “sandbox account”, “client id” and secerate. Where do I find the info for “sandbox email address”, “sandbox merchant id”, “sandbox client id” and “sandbox secret key”? In dashboard-sandbox-accounts it states “email id”, “system generated password”, “user name”, “password” and “signature”. Since I can’t click on “connect to paypal sandbox” I’ll need to enter in the sandbox credentials manually.

However, like I mentioned above, if I try it on my old macbook, the paypal pop up wont show and I’ll get the error message. When I do so, I am able to connect and accept payments on my pc (haven’t actually tested a payment, however the paypal pop up loads fine so I’m hoping it works). I can click on “toggle to manual credential input” to put in my live credentials.

But each time I do so, it tells me I need to revise my current business account and begins asking questions about creating a new account. If I click on that button, I’ll enter in my site info or the sandbox info I found on my paybal developer dashboard under sandbox-accounts. In Woocommerce-Settings-Payments-Paypal… It won’t allow me to “connect to paypal” or “connect to paypal sandbox”. In order to further trouble shoot, I would like to test out my paypal connection using sandbox but I’m having issues connecting to sandbox. Does woocommerce with paypal payments work on an older macbook pro using OSX 10.9.5? After setting up paypal, it works on my pc but if I go to check on my older mackbook I get the following error when I click on the paypal button to pay: “ The requested action could not be performed, semantically incorrect, or failed business validation.
