No Entries Found in blog

I have problem with Ceceppa im using ceceppa-multilingua.1.3.27 as i already told on your website higher crash my site.

I have 2 languages on my site and my theme can use up to 3. the problem is that it looks like site is using 3 languages default, english and polish.
Then when i go to news it redirect to &lang=en where i put a search button after I use search the link on the top of site is changing from news/&lang=en to /news/ and if show No Entries Found.
whatever i click the News will not show until i press the flag and change the language. this problem dont appear when i chose second language and then search which mean that the english and default language are not same but separated.

I also had to disable Filter search
As i had no entries found in any language in the blog.

Display as dropdown need to be disabled or i have no entries found.
