profile pages give 404 error

A bit about what i am trying to achieve:

I have just set up a wordpress multisite with subdomains(main site: schoolcommunity.co.za which uses the herald theme and subsite http://eastrandacademyofexcellence.schoolcommunitysa.co.za running the kleo template(all other future subsites will also use kleo)). The main site is supposed to be where a user comes and logs in and can then access the subsites. From here the user based on their access level can access different parts of the subsite as well as message others on the network, view their profile, etc.

What the issue is:

When I try access the ‘my profile page’, messages page (basically anything you would access through the admin bar-my account in the top right) I get a 404 error. I have a buddypress error banner stating that i need to change from my default permalinks structure however when i do this all my published pages start also giving 404 errors and i still cannot access the profile pages.

All plugins and themes are updated.

Below are the htaccess settings:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ /wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]

php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300
php_value max_input_time 300

Below are the wp-config settings:

define( ‘WP_ALLOW_MULTISITE’, true );
define(‘MULTISITE’, true);
define(‘SUBDOMAIN_INSTALL’, true);
define(‘DOMAIN_CURRENT_SITE’, ‘schoolcommunitysa.co.za’);
define(‘PATH_CURRENT_SITE’, ‘/’);
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOG_ID_CURRENT_SITE’, 1);

Please Let me know should you require any furthur details.

Thanks for the help in advance
