Do you have a object-cache.php in your wp-content directory? If so, rename it. But first make sure the upgrade replaced all new files. Upgrade per FTP and watch out for failed transfers.
If content displays within WordPress itself when you are logged into the dashboard but does not display on the front end of your site it is almost always a theme problem. If you have access to server logs, such as error logs in cPanel, you can see what errors are being thrown up. The easy … Read more
I ran into this as well… I am using the SQL query, but not the wpfp_list_most_favorited() function, so this may or may not work for you, but worth a shot. Try updating the SQL query in wp-favorite-posts.php (around line 206) from: $query = “SELECT post_id, meta_value, post_status FROM $wpdb->postmeta”; To: $query = “SELECT post_id, meta_value, … Read more
Check the filter update_feedback, he works after the update and you can use for all stuff after an update. An example plugin can you find in this trunk.

Never try to upgrade that many versions in a single step! You will need to carry out a series of smaller, manual, upgrades: 2.7 -> 2.8 -> 2.9 -> 3.0 -> 3.2 -> 3.3.1 ->3.3 I would deactivate all plugins and switch to default theme when you get to current version, switch themes to what … Read more
wp-content should be 755, otherwise WordPress will think it has global write access, and won’t fallback to the FTP filesystem method if it doesn’t. Might be worth checking if PHP is running in safe mode – this can also be the troublemaker (though I’m aware WordPress can still upgrade with it on).
