Article not displays in joomla

Yesterday i found that in inner pages of my website pages are not displays(in joomla). Thou, home page (index page) is working fine. So i have started googling for this. Here is solution that works for me.

1.Check whether article is publish or not. (In my case article is publish, but also it is not diplaying in website)

2.Update your joomla in latest version (please this step is always important. Whethere you have face any problem or not).

3.Here is solution that works, i update file of libraries folder (all files).
