tried to change by zara the language and I'm not getting, can you tell me where I can locate this language?

@paulinoromeira
That is not theme translation, probably belongs to osclass core.

I went to the oc-content/languages/en_US in the core was there "check with seller" switched to the combine but only modified the text in time to make the publication (the text after you put the value)

but in this item-post.php as <?php _e('Check with seller', 'zara'); ?> tried to change around here cannot.

@paulinoromeira
As you can see, this string is correctly placed and no issue there.

thank!
