[SOVED] PayPal ExpressCheckout Error

[khaledsaied]

Hi. I am running Prestashop 1.5.6.1 and Paypal version 3.6.1 

I get this error when I click on the PayPal checkout logo on my store:

Notice: Trying to get property of non-object in /home/buyzaapt/public_html/modules/paypal/express_checkout/process.php on line 125

Fatal error: Uncaught exception 'PrestaShopException' with message 'Property Cart->id_currency is empty' in /home/buyzaapt/public_html/classes/ObjectModel.php:837 Stack trace: #0 /home/buyzaapt/public_html/classes/ObjectModel.php(255): ObjectModelCore->validateFields() #1 /home/buyzaapt/public_html/classes/ObjectModel.php(596): ObjectModelCore->getFields() #2 /home/buyzaapt/public_html/classes/Cart.php(195): ObjectModelCore->update() #3 /home/buyzaapt/public_html/modules/paypal/express_checkout/process.php(126): CartCore->update() #4 /home/buyzaapt/public_html/modules/paypal/express_checkout/process.php(140): PaypalExpressCheckout->initParameters(true) #5 /home/buyzaapt/public_html/modules/paypal/express_checkout/payment.php(134): PaypalExpressCheckout->setExpressCheckout() #6 {main} thrown in /home/buyzaapt/public_html/classes/ObjectModel.php on line 837 

 

The site where I click on the button: http://buyzaaptv.dk/tilbehoer/10-zaaptv-hdmi-409n.html

 

 

Can anyone help with this, please?

I solved this error with deleting PayPal Module and afterwards reinstalling the PayPal Module again.

How can I delete this post? Thanks.
