Adding
AddHandler application/x-httpd-php5 .php
in your .htaccess file only works if on the server there is PHP 5.x installed. Many servers have both PHP 4 and PHP 5 installed and this is a way to switch between them. For the other hosting servers that won't do any good.

A workaround for this error is using utf8_decode($text) instead of using the default html_entity_decode() used in the plugins.
This would work fine only if your blog is utf8 encoded, but the error only hapens (as i could see from the php bug page) when you try to decode utf8 text, and it is default to Wordpress anyway.
eg: for the post rating plugin, replace the line 573 from wp-postratings.php from:
$text=html_entity_decode($text,ENT_QUOTES,get_option(’blog_charset’));
to:
$text = utf8_decode($text);
Of course, you should check if the blog really is utf8 before doing so.
