This component uses an intermediate certificate here:
/administrator/components/com_sppagebuilder/assets/vendor/facebook/graph-sdk/src/Facebook/HttpClients/FacebookCurlHttpClient.php: CURLOPT_CAINFO => DIR . '/certs/DigiCertHighAssuranceEVRootCA.pem', located at:
/administrator/components/com_sppagebuilder/assets/vendor/facebook/graph-sdk/src/Facebook/HttpClients/certs/DigiCertHighAssuranceEVRootCA.pem This certificate is not up to date and is therefore receiving this error.
As a temporary workaround, you can comment out this line in the FacebookCurlHttpClient.php file: CURLOPT_CAINFO => DIR . '/certs/DigiCertHighAssuranceEVRootCA.pem',
And after commeted that line, I hope it will work.
Thanks
