Annoyingly, when you close a topic in bbPress, the text becomes grey instead of black. This is bad for SEO. To stop closed topics becoming grey in bbPress:
- Edit the /wp-content/plugins/bbpress/templates/default/css/bbpress.css file in a text editor
- Find #bbpress-forums .status-closed
- Below this code you will find color: #ccc;
- Change #ccc to become #000
Text in closed topics will now be black instead of grey.
If closed topic text hasn’t changed from grey to black, you may need to refresh your browser / server cache to clear out the old CSS.
