Re: Translation files not being picked up
Hi Philpeter,
The language files go only in /wp-content/plugins/buddypress/bp-languages (do not create this folder, use the existing one) and should not be copied or placed anywhere else.
Move your “bp-custom.php” file out of /wp-content/plugins/buddypress/ and into /wp-content/plugins/.
If you are still having trouble, make sure the MO version of the file was created correctly.
