...unless of course you were trying to do the new site installation in a folder that already had an .htaccess file in it.
If I am understanding here, that seems to have been my case. While using SimpleScripts at my BlueHost Dashboard, I had to disable BPS in order to do the installation of site_2 in my public_html folder...and here is the .htaccess still present within that folder even while BPS yet remains disabled:
# BULLETPROOF PRO 5.D DEFAULT .HTACCESS
# If you edit the line of code above you will see error messages on the BPS Security Status page
# WARNING!!! THE default.htaccess FILE DOES NOT PROTECT YOUR WEBSITE AGAINST HACKERS
# This is a standard generic htaccess file that does NOT provide any website security
# The DEFAULT .HTACCESS file should be used for testing and troubleshooting purposes only
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
I might never understand how all of this works, but now I surely do know my public_mtml folder is well-covered while BPS is at work!
