Osclasswizards Translation " Next, Previous " words, How?

I use Osclasswizards theme, on search page ( categories ) bottom of items , there is pagination…
There 2 words " previous, next ".

Unfortunatelly I can not find wherefrom I can translate to Turkish or other languages those 2 words.
I have already checked language folder PO files. No such a word…I have manually inserted it. But it is not affecting and it always shown as English…

Did you resolve this problem? if yes, how you did that?
