This error generally comes up during the initial install and when that happens, it's usually down to incompatibilities between the PHP MySQL client library and the MySQL server (older client library).

This could be down to something related to style customizations (and properties that changed type). Ideally, I would recommend reverting to a pre-upgrade backup and removing any custom styles to see if that resolves the issue (rebuilding the master data in the old version should be sufficient to trigger it).

You may be able to get away with it by putting:
Code:
$config['checkVersion'] = false;
Into config.php to access your control panel, but that's not definitive. From there, you could try exporting your styles and removing them one by one to see if that helps. I would strongly recommend taking another backup before doing this though.
