Following is chat record with my host company see if that helps :
I am seeing a PHP Fatal error.
[error] [client 121.223.245.129] PHP Fatal error: Call to a member function Execute() on a non-object in /var/www/vhosts/sxxxx/httpdocs/includes/functions/sessions.php on line 61, referer: http://xxxx/admin/login.php
That indicates that something in the code has an issue but not server
It could be that a file has not been uploaded or that the file was uploaded in ascii mode and it should have been uploaded in binary mode

This is most likely causes by going to php 5.x on your server ...

In the two sessions.php functions, you can try adding:

    function _sess_write($key, $val) {
      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);
      }

Hi Ajeh:

I have had the same problem when my hoster changed to PHP 5.2.

I've tried the solution you said and all work perfect again-

But I have a doubt, you are talking of 2 sessions.php. I got the message in public_html/cart/includes/functions/session.php, that was where I got the error into admin panel, but I was having the same error every time than an user tried to log, apparently no errors on login, but the user couldn't get into, so no possiblity to purchase either.

I changed also the public_html/cart/admin/includes/functions/sessions.php case that this one were the other file.

Really, with only the first change all back to work again(adminn panel and users login , but I have the doubt if more sessions.php are affected for the PHP5.2 bug.

Any ideas?

Thanks for your help

In the Admin I used for:
/admin/includes/functions/sessions.php

    function _sess_write($key, $val) {
      global $SESS_LIFE, $db;
      if (!is_object($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);
      }

Many thanks, that was the way I did.
