Latest update causes signature mismatch

Hey @carlaturner91,

It’s possible that the issue may be the result of your host changing IPs to a new address that isn’t seen as ‘trusted’- which is a pretty common issue (as hosts change IPs for various reasons).

If you can enable logging in the Payfast settings and make a test payment, that can help confirm the issue. If this is the case, you can try adding the following code to your site, preferably via something like the free Code Snippets plugin:

add_filter( 'woocommerce_gateway_payfast_is_valid_ip', '__return_true' );

Let us know if this helps or if the issue continues. Thanks!

Since we haven’t heard back in a while, I’m going to go ahead and close this thread. However, if the suggestion above doesn’t help, please feel free to open a new thread. Thanks!
