Thank you for your feed back. We fix the forum, it should work now.
To add an image preview to your post you need to use the “feature” image.
We will check the theme again to see what string we missed and we’ll add the translation functions. Notice that there are more the one function for the translation files you need to use “__;_e;_n:1,2;_x:1,2c;_ex:1,2c;_c:2c,1;_nx:4c,1,2;_n_noop:1,2;_nx_noop:4c,1,2;esc_attr__;esc_attr_x:1,2c;esc_attr_e;esc_html__;”
