I using paypal express got error message:
app/code/core/Mage/Paypal/Controller/Express/Abstract.php on line 142
I del the folder “paypal” at the template and paypal.xml at the layout folder, now everything is working,
Aaron, please check it
Having this same issue. I deleted the same files and got one part to work then I get to the next step of checking out and get the error Unable to Place order. I am using HelloMinty. Not sure if it is in the template or an error in magento but if you could check it out Aaron.
