Hello,  
  
  
  
Can anyone please help me? Everything was working fine until just now when I saw this error:

Quote:

Fatal error: Class 'PDO' not found in /home/rramindia/public\_html/marketing/vendor/doctrine/dbal/lib/Doctrine/DBAL/DriverManager.php on line 155

  
Not sure if this is related or not...The only thing that I can think of that has changed before me noticing this error is that I increased the memory\_limit in php.ini  
  
  
Thanks.

Make sure that your server has installed and enabled the php-pdo extension.
