Having recently setup a site on Buddypress, I wanted to remove the admin menubar since it just didn’t fit my site. However, it turned out to be a big deal only because, of the two simplest articles I found on how to achieve this, one was wrong and the other required a bit more information.
To hide the admin menubar in a Buddypress installation, you’ll want to either alter or create a file called “bp-custom.php” in the wp-content/plugins folder on your server. To clarify, if this file doesn’t exist in that folder, you’ll have to create it.
In this “bp-custom.php” file, you’ll want to copy and paste the following:
define('BP_DISABLE_ADMIN_BAR', true);
If the file is empty, just copy and paste it right into that empty file and if the file already has more in it, this can be pasted safely at the beginning or end of the file.
