Problem : After search operation, I can not access second or third result pages.
 

Hello everybody,
My problem is about searching a word in the site. When I search a page, the results are listed. Wordpress shows 5 result in a page so it creates more than one tab for result pages. But for example I try to access the second page clicking the tab, it shows error page. For example:
I searched "dilek" in my site.
The url is : http://mysite.com/?s=dilek&submit=
Attachment 2470

After clicking the next or 2 it shows this page :
URL is : http://mysite.com/?attachment_id=2&s=dilek&submit

Attachment 2471
So please help me to fix this problem please...

Have you tried after disabling ALL plugins?
What is the URL?

The url is http://iibf.deu.edu.tr You can search for word "AYDIN"

Have you tried after disabling ALL plugins?

Yes I deactivate and try again but the result is same.

I did a search on AYDIN, and when I clicked on the 2 tab for the second page, it looked fine:

http://i192.photobucket.com/albums/z...dPress/DEU.jpg

This was the address:
http://iibf.deu.edu.tr/en/page/2/?s=aydin&submit

when I try it on a vanilla site, teh search works fine. I would have to see your site with all plugins shutoff.

Have you made any changes to any of the virtual templates or theme code?

I found the problem. I use Polylang extension in my site. I also activate permealinks. So when I search a word in turkish language url is :

http://iibf.deu.edu.tr/?s=AYDIN&submit=

This shows results. But clicking second page with url :
http://iibf.deu.edu.tr/page/2/?s=AYDIN&submit is not working.

Url should be :
http://iibf.deu.edu.tr/tr/page/2/?s=AYDIN&submit

I dont know how can I solve this problem. Is it about search code, wordpress or polylang extension?

If you shut off the plugin and the search works, it's most likely a plugin issue
