I suggest to contact your hosting tech support and let them know. </p> https://www.machform.com/forums/topic/fatal-error-mysql_attr_use_buffered_query-after-php-update#post-24149 Thu, 01 Oct 2015 03:46:48 +0000 Batdelfuego 24149@https://www.machform.com/forums/ <p>Hi!</p> <p>I've just updated PHP to version 5.5.29 on my server and I'm getting this error on a client's MachForm install:</p> <p>Fatal error: Undefined class constant 'MYSQL_ATTR_USE_BUFFERED_QUERY' in /web/sites/digitalconvul/gdi.com/forms/includes/db-core.php on line 13</p> <p>I think I'm still using MachForm 2 for this client. (can't seem to find the info in the config.php).<br /> If I update to MachForm 4 will I get some problems?<br /> (I already bought a Machform 4 update).</p> <p>Thanks!<br /> David </p>
