Whoops\Exception\ErrorException: Module 'pdo_mysql' already loaded in Unknown:0

I recently migrated to a new server and although I copied my apache configuration from the old server, I am still getting some issues with WHMCS. 

This all started with an email for a failed cron job which stated

 

Your WHMCS is configured to perform the Daily System Cron during the hour of 12 am. However, the Daily System Cron did not execute within that hour as expected.

This may be due to the scheduled time specified in your web hosting control panel's cron entry. Please ensure your web hosting control panel executes the WHMCS System Cron (cron.php) at least once during the hour of 12 am.

I proceeded to try and fix this, making sure the crons were setup and all, I couldn't find an issue. So I thought it might be my PHP Version, I double checked that WHMCS supports PHP 7.2 and proceeded to apply it to WHMCS. 
I also had to install the Ioncube loader for PHP 7.2. 

Now when I go to most WHMCS pages inside the admin area I get the following error. 

Whoops\Exception\ErrorException: Module 'pdo_mysql' already loaded in Unknown:0
Stack trace:
#0 /home/XXX/public_html/vendor/whmcs/whmcs-foundation/lib/Utility/Error/Run.php(0): WHMCS\Utility\Error\Run->handleError(32, 'Module 'pdo_mys...', 'Unknown', 0)
#1 [internal function]: WHMCS\Utility\Error\Run->handleShutdown()
#2 {main}

This error goes away after commenting the following out in my .htaccess

<IfModule mime_module>
  AddType application/x-httpd-ea-php72 .php .php7 .phtml
</IfModule>

But then I get the following error when trying to check for updates in WHMCS

Unable to Perform Automatic Updates
Automatic Updates require the allow_url_fopen setting to be enabled in your PHP configuration.

So basically, If I uncomment the .htaccess line, WHMCS Update doesn't show the "Allow_url" error. But the other pages have the "pdo_sql" error. And if I comment the .htaccess line out, I lose the "pdo_sql" error but gain the "allow_url" error. 

I'll lodge a support ticket and get back with the results if no one here can figure it out. 

Thanks

I found a second php.ini file inside my admin directory which was loading pdo_mysql, I removed that and it's fixed the errors, but I still have the cron issue present.

Issue Resolved: config.php had the incorrect path to the WHMCS directory inside the custom crons folder. 
then ran:

php -q /home/accountname/custom_crons_folder/cron.php all --force -vvv

And it fixed the cron issues.
