paypal stopped working not passing data

[cliqadam]

Paypal Module stopped passing info to the confirmation page 

everything was ok and nothing was edited on the codes or modules 

 

all of the sudden clients started mailing us that they see a 500 error on confirmation page 

 

after doing some tests i also see that paypal is not registering the test purchases. (could this be on paypal's end?) 

 

 

 

these are the debug errors  using PayPal v3.6.6 - by PrestaShop 

right after clicking on continue button on paypal

that version of the module is too old, upgrade to a more recent version.
