I have the same question…thanks.
Unfortunately, just using CSS won’t cut it as the titles do not have unique ID’s or classes. If you put `body.directory h3 {display:none;}` even the widget titles will disappear along with page titles of activity index page (when logged out).
The alternative, If you have a child theme of bp-default theme:
– Create three folders in your child theme folder namely: groups, members and forums.
– Copy over groups/index.php from bp-default theme to your child theme
– Copy over members/index.php from bp-default theme to your child theme
– Copy over forums/index.php from bp-default theme to your child theme
– Open up the files you copied over to the different folders in your child theme and delete the titles. Note: for groups/index.php, if you also want to delete the “Create Groups” link, delete from start of `
to end of `
`. Otherwise, leave the link for Create Groups link.
If you used BP Template Pack plugin and transferred 6 folders with BP template files, just open up the files mentioned above, make revisions and upload to server making sure you upload to correct folder.
