At times your WHMCS cron won’t complete if you’re using the Payfast module.
On cPanel, you can force the cron like so:
/opt/cpanel/ea-php81/root/usr/bin/php /home/username/whmcs-private-files/username/crons/cron.php all -F -vvvv
Note the all, -F, and -vvvv switches.
Then you’ll see this:
Connection #0 to host api.payfast.co.za left intact 6/36 [▓▓▓▓░░░░░░░░░░░░░░░░░░░░░░░░] 16% 15 secs/1 min 54.5 MiBTypeError: fclose(): supplied resource is not a valid stream resource in /home/username/public_html/modules/gateways/payfast/vendor/payfast/payfast-common/src/PayfastCommon.php:172
Fix the code vendor’s code by commenting out line 185:
mc -e /home/username/public_html/modules/gateways/payfast/vendor/payfast/payfast-common/src/PayfastCommon.php:185
and 172:
mc -e /home/username/public_html/modules/gateways/payfast/vendor/payfast/payfast-common/src/PayfastCommon.php:172
Now your cron will complete. Hopefully Payfast will shed light on this topic one day.
