Magento

I am attempting my first install of Magento (latest version), but I get this error after accepting the terms and conditions and clicking continue:

Fatal error: Mage_Core_Model_Session_Abstract::getMessages() [<a href=’function.Mage-Core-Model-Session-Abstract-getMessages’>function.Mage-Core-Model-Session-Abstract-getMessages</a>]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Mage_Core_Model_Message_Collection" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in C:\inetpub\magento\app\code\core\Mage\Core\Model\Session\Abstract.php on line 87

This happens on this page: http://magento/index.php/install/wizard/locale/

This is what I’m running:

Windows XP Professional
Apache 1.3.39
MySQL 5.0.45
PHP Version 5.2.5
PDO Driver for MySQL, client library = version 5.0.45
magic_quotes_gpc = Off
short_open_tag = On

I’ve seen this error once on the Brazillian forum, but I couldn’t work out what they were suggesting was the solution.

Any help would be greatly appreciated.

I’m essentially having the same issue, anyone have any solutions? I’m re-uploading the newest beta right now to see if I somehow just missed a file.

Unfortunately I can’t report that I’ve solved this problem. The Magento install process has a long way to go before it can be considered “seamless”.

Would be nice if the first page of the install checked all the dependencies and told you exactly what was wrong with your setup.

Hi,

I have had this error message when installing

Fatal error: Call to a member function getIdFieldName() on a non-object in /content/DesignerPlus/g/o/good-cheap-affordable-web-design.co.uk/web/magento/app/code/core/Mage/Core/Model/Abstract.php on line 118

can anyone help

Got exactly the same problem:

Fatal error: Mage_Core_Model_Session_Abstract::getMessages() [<a href=’function.Mage-Core-Model-Session-Abstract-getMessages’>function.Mage-Core-Model-Session-Abstract-getMessages</a>]: The script tried to execute a method or access a property of an incomplete object.

Setup is VMWare session running fedora8 linux
Apache 2.0.61
PHP 5.2.4
MySQL 5.0.45
PDO for MySQL

At the moment, just followed the basic install instructions. Any feedback before i start dissecting?

Thanks in advance

For all you guys out there that got this problem:

Setting session.auto-start to OFF in the .htaccess file or php.ini solves this problem. Sessions cannot be created BEFORE objects that the session depends upon are instantiated. A call to session_start() in the code ensures sessions are started for the request, probably after all the dependencies have been loaded.

hey gang
good to see RSA being represented.

I managed to get magento installed just fine.
my service provide has it as a one click install ( media temple : great service )

I’ve been trying for a couple of days not figure out how to interface with a payment gateway.

I understand some of you guys managed to do it.
Is there any chance you could share some of the source on how you accomplished this?

regards

Hi Maxumis

This is being discussed in the South African group: http://www.magentocommerce.com/group/view/220
Progress is slow at the moment, but we’re getting there.

Hi Blade,

What payment gateways are you interested in?
BTW. What’s modelbase going to do with Magento?

Also, Andrew, have you managed to sort out your problem?

Willo

Has anyone had any success solving this issue

Magento was working fine my local and live servers at Magento 1.0 but as soon as I upgraded to 1.0.19870.4 the LIVE server died and gave me this error, but the local server still works like a charm?  Any ideas?
