2. SSH into your server and enter these two commands to rename/backup the old files :

mv /usr/local/vesta/ssl/certificate.crt /usr/local/vesta/ssl/unusable.crt
mv /usr/local/vesta/ssl/certificate.key /usr/local/vesta/ssl/unusable.key

3. Create symlinks to point to the new ones (Replace admin with your admin username and server.domain.com with your server’s hostname (FQDN).

ln -s /home/admin/conf/web/ssl.server.domain.com.crt /usr/local/vesta/ssl/certificate.crt

<button onClick="fbq('track', 'Purchase');">Button Text</button>
Or you could create a function that pushes the event. The advantage is if you have multiple HTML elements, you can call a single function when someone clicks any of them; you don't have to define individual onClick element.

For example, to push the event:

<script>
function onClick() {
fbq('track', 'Purchase');
};
</script>
