Mi è successa la stessa cosa per un'aggiornamento da 3.02 a 3.2.2.
Ho trovato interessante questo topic :
http://forum.joomla.org/viewtopic.php?f=710&t=825407#p3103165ed ho risolto con:

"Rename your file remember.php to rememberBAK.php so it looks like this
/plugins/system/remember/rememberBAK.php
Find a copy of Joomla 3.x.x and make a copy of the remember.php
FTP the file to your folder
/plugins/system/remember/remember.php
Now access your admin panel
Go to Extensions -> Extension Manage -> Database
Click Fix
Now go to ftp, delete the remember.php that you uploaded and rename the original one to it's correct state."

e poi con:
########
"So, if you get the error on the "Fix" database option you should create the table "xxxx_content_types" in your database (mySQL) by the following SQL query:
CREATE TABLE IF NOT EXISTS `xxxx_content_types` (
`id` int(11) NOT NULL,
`content_history_options` varchar(5120) NOT NULL COMMENT 'JSON string for com_contenthistory options'
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
where xxxx is your dbprefix in your database, e.g. 'd3hrs_'.
You must change xxxx to your dbprefix!!!"
