I have only tested this on one of my development sites and it is working for me on my host and does not appear to have broken anything else. Here is a plugin that contains this 'fix':ĭISCLAIMER: I take no responsibility and assume no liability if this causes your server to explode, catch on fire and burn down the data centre, instantiate a singularity and cause the universe to implode (or anything else bad that might happen). I will start work on a plugin to change this behaviour if possible, though I would prefer to see this issue addressed in the core. WordPress functions, as called by WooCommerce default to using curl with HTTP/1.0 and TLS 1.0. Thanks for any additional help and weight you can add to the case to be made to Auttomatic. I suggest we head this off at the pass while we have the opportunity. On June 17th 2016 they will all stop working.

This will affect every single WooCommerce/WordPress site that is hosted on your systems. Perhaps if the request comes from someone like Hostgator they will listen? I have not had the best of luck getting modifications accepted to the wordpress core in the past. So, then we need to get the WordPress core code modified to use the proper curl settings. WooCoommerce uses core WordPress functions to post to the PayPal IPN url. It is defaulting to TLS 1.0, but you can use up to TLS 1.2 if you specify it in your code. You would need to contact the developer of the plugin or your site to have them update the cURLOPT to use TLS 1.2 specifically. In order to utilize the TLS 1.2 cipher in accordance with Paypals new policies. I have spoken with my Service provider and they say that TLS 1.2 is installed.WordPress' functions as called by WooCoomerce can no longer use the paypal sandbox and as of it will no longer be able to talk to the production paypal systems. On the paypal app, configure > general page if verify SSL is set to True and I click the 'Test connection' button then I get a failure on the test, the error message says to check that TLS 1.2 is enabled.

Having not had any luck with getting PayPal to work I have carried out the test below. I have just installed a virgin OSCommerce 2.3.4.1 instance and added the PayPal app and updated it using the automatic update feature.
