if the problem is only with the profile settings tab, then copy the profile.php and profile folder from the location:
“plugins/buddypress/bp-themes/bp-default/members/single/”
to the following location:
“themes/your-current-theme/members/single/”
This will correct the problem
Thanks for the tip, but it did not work for me. Have the same problem like fswd…
Any other solutions?
I also tried this solution, but it did not work for me too.
Following up on @frenx4u, is your theme a child theme of bp-default, or did you adapt it for BP use with the BuddyPress Template Pack? If the latter, you will probably have to do what frenx4u suggests.
It may be caused by one of the plugins you have installed. remove all the cache. if still does not work then move all the plugins except the buddypress to a backup folder and try bringing back one plugin after another.

Member settings pages are blank
BuddyPress 1.5 comes with brand-new templates so you can style your member settings pages. However, if you’re using an older child theme, you will need to copy over these templates to your WP theme. To fix this problem, copy over the folder [/plugins/buddypress/bp-themes/bp-default/members/single/settings/] directly to your WP theme’s folder.
This has been resolved using the suggested advice: https://codex.buddypress.org/releases/1-5-developer-and-designer-information/#theme
Thanks everyone… Got there in the end!!
