Re: Unable to install
– delete all buddypress folder by ftp
– log off wp-admin
– log in on wp-admin
– upload by ftp the buddypress folder (make shure you put on wp-content/plugins) after upload you should have wp-content/plugins/buddypress/”a lot of files and folders”)
– Check plugins again on wp-admin
If you have any error on ftp (deleting the files) :
check the user permissions, depending on server configuration, the files could be with apache permissions instead of your user.
If you are on a sharing hosting ask your support to check the file permissions for you.
