Max size publish limit

[Spheerys]

Hi,

I have a customer which have a blog.
In this blog, he want to publish very long post, but he got "Error 500, Internal server error"

I change the limits in /var/www/fcgi/domain.tld/php5/php.ini and restarted apache2, but he always have the same problem.

Here the content of the php.ini of the domain : http://pastebin.com/P338ecNT

And with a phpinfo();, I can see that my modifications in php.ini are good.

What's wrong ?
