My website has SSL/SHA2, I'm using PS1.6.0.9 default theme and PayPal EU module. And no third party modules.
How do I configure my SSL to TLS? Should I get it done before I update the PayPal module? Support team asked me to post this question as they the experts in the community might have a workaround solution.
What else do I need to do before I update the PayPal EU module on PS1.6?

Hello Chris_L, Thanks for the question. According to a post in the PrestaShop support forum, this Paypal was disabling their SSL 3.0 module on December 3. The configuration change that they suggest is all discussed in this post. The changes recommended by another PrestaShop 1.6.0.9 user are:
    Edit modules/paypal/api/paypal_connect.php line 88 - change number 3 to 4 for CURLOPT_SSLVERSION: from: @curl_setopt($ch, CURLOPT_SSLVERSION, 3); to @curl_setopt($ch, CURLOPT_SSLVERSION, 4);
They recommend that you test this in the Paypal sandbox. Please reference the post if you have any further questions or comments. Regards, Arnel C.
