www.address.com/profile/username.com then i am getting internal server error. How can i fix this problem anyone can help me here please ?

RewriteRule ^profile/([\w-]+)/?$ profile.php?username=$1 [L,QSA]  
RewriteRule ^profile/(followers|friends|saved)/([\w-]+)/?$ $1.php?username=$2 [L,QSA]

Answer 1

You may make your regex more open like these rules:

RewriteRule ^profile/([^/]+)/?$ profile.php?username=$1 [L,QSA,NC]  
RewriteRule ^profile/(followers|friends|saved)/([^/]+)/?$ $1.php?username=$2 [L,QSA,NC]

[^/] matches any character that is not /
