For me it shows: “10 Juli. 2015 in Uncategorized by Martonno” for a post
with custom date setting “j. F Y” in “Settings > General”.
If it doesn’t work for you, you can add your preffered date format through a function in your child-themes function.php
add_filter('tc_meta_date_format', 'custom_date_function');
function custom_date_function(){
return 'j. F Y';
}
This should show: “10. Juli 2015 in Uncategorized by Martonno”
The “by %1$s” is currently not translated due to a missing translation in the .po.
For a comment it shows: “18. Mai 2015 auf 13:14”, caused by an error in the translation.
“%1$s at %2$s” is translated to “%1$s auf %2$s”, but should be translated to “%1$s um %2$s” for usage in class-content-comments.php
/* translators: 1: date, 2: time */
sprintf( __( '%1$s at %2$s' , 'customizr' ), get_comment_date(), get_comment_time() )
Hope this will be fixed in next release.
