Fatal error: Call to a member function Execute() on a non-object

I have had this error for a while now, but haven't had the time to attempt to fix it. I decided to go ahead and set up a new ZenCart site, and work on some custom templates. However I can't log into the admin section at all. The admin login screen and the cart front page both display this error.Fatal error: Call to a member function Execute() on a non-object in /var/www/localhost/htdocs/catalog/includes/functions/sessions.php on line 61This is the line in question in the above mentioned file.```
line 61 ### $total = $db->Execute($qid);

Can this be a problem with php or mysql.  I am running php-5.2.2 and mysql-5.0.44.  It seems that this problem started with some system updates a little while back.

TIA................................:smile:

It seems you're using an older version of Zen Cart on a newer version of PHP.

What Zen Cart version did you install?

It seems you're using an older version of Zen Cart on a newer version of PHP.

What Zen Cart version did you install?The Version I have installed is 1.3.7 which appears to be the latest version. I don't remember if I installed the adim patch or not, it's been awhile. I will download a fresh copy of the latest patched version and do a clean install.

Dr Byte I'm getting the very same error since moving across to a new server.

Upgrading to the newer version is something I'd like to avoid right at the moment as my 'customisations' weren't written as portably as I would have liked.

Any advice?

from the version.php file..

Major Version 1..

Minor version.. 3.0.2

You're probably experiencing the PHP5.2 incompatibility problems others have had when using ZC versions prior to v1.3.6 (where a workaround was added to handle a PHP 5.2 quirk). The fix is documented elsewhere on the forums: http://www.zen-cart.com/forum/showthread.php?t=50534#post287587

Or there are other thoughts discussed here:

Thanks DrByte - that fix worked perfectly.

For others that have stumbled across this thread via a search as I did, DrBytes Solution is below -

b. edit /includes/functions/sessions.php and /admin/includes/functions/sessions.php

Code:
function _sess_write($key, $val) {
global $db;
global $SESS_LIFE;

change to:

Code:
function _sess_write($key, $val) {
// The following is only to work around a PHP 5.2.0 bug:
global $db;
if (!is_object($db)) {
//PHP 5.2.0 bug workaround ...
$db = new queryFactory();
$db->connect(DB_SERVER, DB_SERVER_USERNAME, DB_SERVER_PASSWORD, DB_DATABASE, USE_PCONNECT, false);
}

  global $SESS_LIFE;Option (b) may or may not be "complete", and has only had preliminary testing. The best fix will be to have PHP fix their bug, of course.

After doing a clean install (version 1.3.7.1), the error is gone, and ZenCart is working properly once again. I must have had an upgrade issue from an older version to the newer. and not caught it...................................:blush:

Thanks for the help..............................:smile:
