 * Hi jakubmajewicz,
    does the issue only happen on your blog page, or does it also
   happen if you try and view the post directly?
 * The only thing that I can think of that could cause something like this is that
   your site contains a function that is replacing a core WordPress function. This
   bad function would either be part of your theme, or another plugin you have installed.
 * Please take a look at my reply to a previous support request. Everything here
   is also relevant to you: [https://wordpress.org/support/topic/error-500-174/#post-13543521](https://wordpress.org/support/topic/error-500-174/#post-13543521)

 * it happens only on my blog page. After publishing i can preview post with the
   quiz. I can go to the post even directly.
 * Everything is good only blog page crashes 😀

 * This points to your theme being the most likely culprit.
 * This [past response](https://wordpress.org/support/topic/error-500-174/#post-13543521)
   will let you know the things you can do to try and track this down, but I’d recommend
   temporarily switching themes first just to see if that resolves the issue (you
   can even try to “preview” a different theme first just to verify.
