Hi @central4allgmail-com,

You can use the following CSS code to hide the time section from the "Recent Topics" widget.

p.postuser > span {
   display: none !important;
}

In the case of the "Recent Posts widget", there is no simple solution I can post here. You should either hide the div with ".postuser" class (it'll hide the reply author as well) or you'll need to modify the  wpForo_Widget_recent_replies class, it can be found in the wp-content/plugins/wpforo/wpf-includes/functions-template.php file. 

thank you

that css isn't working time in recent topics widgets is still showing. Editing the wp-content/plugins/wpforo/wpf-includes/functions-template.php file the time was removed from the topics widget. Which file needs to be changed to remove it from the posts widget?

Or maybe some different css?

It was a caching issue, it's fixed now
