Wrong datatype for second argument after updating to 1.1.6

Could you go in settings->languages then choose the settings tab and just click on “save changes” and tell me if the warning disappeared ?

Do you remember from which version you did upgrade?

The problem didn’t disappear…
I’m not sure if I updated from the 1.1.4 or the 1.1.5, I think the first but I’m sure that it’s one one these versions.

Let’s use brute force then.

Could you go edit the file polylang/include/auto-translate.php at line 16 and replace:

if (!empty($qv['post_type']) && !(is_array($qv['post_type']) && array_intersect($qv['post_type'], $polylang->post_types) || in_array($qv['post_type'], $polylang->post_types)))

by

if (!empty($qv['post_type']) && !empty($polylang->post_types) && !(is_array($qv['post_type']) && array_intersect($qv['post_type'], $polylang->post_types) || in_array($qv['post_type'], $polylang->post_types)))

Perfect! Now it works, thank you!
I have another question please: I don’t translate all the contents, usually the blog contents are only in Italian.
So what can I do to show the default content language if there’s no translation?
I already read this page
But I really don’t understand where I should modify the loop and how.
I’m using the “Stendhal” theme.
Thanks again.

The best person to help you how to customize your theme is the theme author himself. He can guide you to find the file to modify (giving him the example code provided in the mentioned link).

ok, thank you very much.
