Hi Sebastian,
Please accept my apologies for the late reply.
The publication date display is a theme-specific, so in some theme it will show and in others not.
If you know your way around WordPress, you can fix this relatively easy:
- From your browser, inspect the HTML/CSS for the publication-date in a regular post.
- grep for a key word(s) from the above at your site’s theme files
- In the found file(s), look for a condition excluding custom posts (e.g. by including only specific post-types).
- Add ‘oi_run_log_post’ to the allowed post types.
I’ve done the above for “Twenty Fifteen” theme, and found this file:
wp-content/themes/twentyfifteen/inc/template-tags.php
It has a twentyfifteen_entry_meta function with this code:
if ( in_array( get_post_type(), array( 'post', 'attachment' ) ) ) {
$time_string = '<time class="entry-date published updated" datetime="%1$s">%2$s</time>';
Updating it to:
if ( in_array( get_post_type(), array( 'post', 'attachment', 'oi_run_log_post' ) ) ) {
$time_string = '<time class="entry-date published updated" datetime="%1$s">%2$s</time>';
fixed it.
If you have problems – tell me what is your site’s theme, and I’ll try to help.
