Hello,

I just did the upgrade from Joomla 3.1.5 to 3.2.0 stable version and get a blank front page. Turning on error message reporting, I get the following “Fatal error: main(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition “JCategoryNode” 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 /home/www/praguepostcom/modules/mod_articles_categories/mod_articles_categories.php on line 29″ and a blank white frontend.

If i delete the mod_articles_categories directory, the front page loads fine, except the categories menu dissapears.

Any advice? I will restore my back up, but eventually, this site will need to keep up with the updates…

Hi Jeff,

I think you have a problem when upgrade Joomla. I would recommend you revert back to Joomla 3.1.5.

You can try to upgrade to Joomla 3.2.1 instead. After upgrade, you can switch to default template of Joomla (Protostar) and check if there is any error.
Once you switch back to JA Wall and still have the problem which does not found on Protostar, then please PM me the FTP, admin credentials, I will try to detect the root of issue.

Please note: you also need to upgarde JA Wall to latest version when you upgrade to Joomla 3.2
