BuddyPress.org

Your second two issues seem to be related to the theme. See https://codex.buddypress.org/theme-development/building-a-buddypress-child-theme/ for how to build a child theme. Member directory templates are members/index.php and members/members-loop.php. Group home page templates are is groups/single/.

I am not sure I understand the first problem. Are you saying that crop isn’t working? Can you describe in more detail what is happening? Also, any details you could provide about your installation would be helpful https://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/when-asking-for-support/

In the future I also suggest giving a more descriptive title to your support forum posts. Everyone who comes here is looking for help, so titling your post ‘heeeeeeelp’ does not tell anyone what it’s about.

It looks like you are having a javascript conflict, which is being caused either by your custom theme, or by a plugin. Deactivate plugins other than BP to see if one of them is causing the problem. If not, try switching back to the BuddyPress Default theme to see if your theme is the culprit.
