In this instance I have an EC2 instance spun up from a BitNami (HVM) AMI.
The default file to edit is
/opt/bitnami/apps/wordpress/conf/htaccess.confMake a backup of the file before you edit.
Add this block anywhere in the file to redirect all author landing pages to the home page.
<Directory /opt/bitnami/apps/wordpress/htdocs/> RedirectMatch 301 "^/author/.*" http://www.yourdomain.com/ </Directory>Customize to your liking if you would rather redirect to a different page.
When you're done editing, run this to restart apache, then test your changes.
sudo /opt/bitnami/ctlscript.sh restart apache/* Joey */
