[Plugin: BulletProof Security] Broke my website

FTP to your website or use your Web Host Control Panel file manager and delete the .htaccess file in your website Root folder that you added your custom .htaccess code too. You will then be able to log into your site and use AutoMagic to create new standard BPS .htaccess files. To check your Server API take a look at the BPS System Info tab.

Sounds like you added invalid custom .htaccess code to the standard BPS Root .htaccess file/code. My guess (based on the limited specific info and details of the actual problem) is that you have a CGI Server API, but you are trying to add php_value and php_flag directives (DSO ONLY) to your .htaccess file, which can ONLY be added to your BPS Root .htaccess file if your Server API type is DSO or LiteSpeed (DSO).

These php_value and php_flag .htaccess directives can ONLY be used if your Server API is DSO.
php_value post_max_size 20M
php_value upload_max_filesize 20M
php_flag file_uploads On

If your Server API type is CGI you will have to edit or create a custom php.ini file and add these directives in that custom php.ini file.
post_max_size = 20M
upload_max_filesize = 20M
file_uploads = On

I contacted my hosting service before The Incident, and was given the following lines. I added the bottom, after htaccess to the .htaccess file. Do you think that was the problem? If so, what would be the proper way to ad it.

file_uploads=1
upload_max_filesize=50M
post_max_size=50M
max_execution_time=-1

htacess:
suPHP_ConfigPath /home/today29/public_html
<Files php.ini>
order allow,deny
deny from all
</Files>

The directives they sent you are for your custom php.ini file and would not go in your .htaccess file. ONLY php_flag and php_value can be used in an .htaccess file and ONLY if your Server API is DSO. Since they sent you these custom php.ini directives then you would need to add these to your custom php.ini file and not your .htaccess file.

Oh i just noticed that you purchased BPS Pro. I will contact you in a minute to take care of this. Thanks.
