2.8.5 Update and New Problems

Hi everyone,
We use WP in operaturkiye.net website.But a few days ageo we updated it to 2.8.5 and after this some [codes] don’t work and given an error like belows.
For example;
http://www.operaturkiye.net/galeri/duvar-kagidi
This page includes a gallery showing a lot of pictures and it is prepared using gallery function.

For example ;
http://www.operaturkiye.net/hakkimizda/iletisim
This page is using for communication and it is prepared by using clean contact plugin.

But two of that functions ans similiars do not work after upgrading to 2.8.5 version.

Do you have any ideo,solution or suggestions to us?

Thanks.
