I use WAMP on a local development environment and am trying to charge a credit card but get the error message:
cURL error 60: SSL certificate problem:
when I run 'var_dump(php_ini_loaded_file());'
I get this output on my page
'C:\Development\bin\apache\apache2.4.33\bin\php.ini' (length=50)'
and to get php to load my cert file I had to edit the php.ini in this path 'C:\Development\bin\apache\apache2.4.33\bin\php.ini'
and add openssl.cafile="C:/Development/bin/php/php7.2.4/extras/ssl/cacert.pem" where I had downloaded and place my cert file from https://curl.haxx.se/docs/caextract.html
am on windows 10, using drupal 8, wamp and php7.2.4
