I forgot to mention. I use both the distro's repository and git version of wikidiff2. If there is any debug steps, I can provide them.

Please provide exact steps to reproduce, and what was upgraded from what to what. Also see https://www.mediawiki.org/wiki/Manual:How_to_debug

Is the wiki public where this problem can be seen?

Did you make sure you add wikidiff2 to your webserver's php.ini file?

@Kunal Mehta, yes I am sure I add it.

@Andre Klapper, I'm not sure which one I should use from those but I tried all of them. Now I see those errors:

We upgraded our server from Ubuntu 12.04 to 14.04 so packages upgraded as well.

PHP: 5.3.10 to 5.5.9 for example. Which application are you asking especially?

And yes it is a public wiki: http://wiki.ubuntu-tr.net

Thanks for your replies.
