So i am using a edited _tk theme one of the things i wanted to remove was the Updated on
line “Posted on 12th January 2017, updated on 12th February 2017 by john” to do this i had to go into template_tags.php and changed these two lines on function _tk_posted_on
Line 200
$ time_string_update = '< time class="updated" datetime="%1$s">%2$s';

< time class="updated" datetime="%1$s">';
and line 210
time_string .= __(', updated on ', '_tk') . $time_string_update;

$time_string .= __('') . $time_string_update;
