I solved the problem
Previous theme used additional format post (post, image, video, gallery, etc.). Tammoo displays posts that have defined the format as plain, so this selective display. Posts were visible, but were not displayed by the function of tammoo:
<? php if (have_posts ()):?>
<? php while (have_posts ()): the_post (); ?>
if (! get_post_format ())
get_template_part (‘format’, ‘standard’);
get_template_part (‘format’, get_post_format ());
So, I changed the theme to the previous, mass changed the format of posts on plain and changed the theme again to tammoo which solved the problem.
