The Divi theme is using the pipe symbol " | " to separate the meta tags:
You may want to change this to something else and, before I share the code, note that this code will change the pipe symbol on all the posts, including single posts, the blog module and all archive/category/search pages.
Please add this code in Divi > Integration > Add code to the < body > (good for tracking codes such as google analytics):
<script>
jQuery(function ($) {
$(document).ready(function () {
var post_meta = $('article .post-meta');
if (post_meta.length) {
post_meta.each(function () {
$(this).html($(this).html().replace(/\|/g, " *"))
})
}
});
});
</script>
Results:
As you can see, I replaced the pipe with a star symbol. Feel free to change the star * character in the code to your desired character or even to text.
