what's wrong with the following htaccess rules - regex

Question

Hi I got an amazing (?) work to fix the error on a site. It was a HTTP 500 error.
It is caused by the htaccess file. But I can't figure out what's wrong with the code. here is the code.
# Use PHP5 Single php.ini as default
#AddHandler application/x-httpd-php5s .php
# The rules below basically say that if the file exists in the tree, just
# serve it; otherwise, go to index.php. This is more future-proof for your
# site, because if you start adding more and more content types, you don't
# need to alter the .htaccess to accomodate them.
# This is an important concept for the Front Controller Pattern which the
# ZF MVC makes use of.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ public/index.php [NC,L]
Redirect 301 /platforms/mt4-ecn http://example.com/
Redirect 301 /partnerships/mt4-to-mt4-bridge http://example.com/
<IfModule mod_suphp.c>
suPHP_ConfigPath /home/aaaecn/public_html
</IfModule>
<Files php.ini>
order allow,deny
deny from all
</Files>
this redirect rules are for zend framework, But I don't have any experience in working with that framework.
I commented all lines and tried now the 500 error is fixed. So I filtered it down by uncommenting.
RewriteRule ^.*$ - [NC,L]
this line is causing the error, but removing this giving invalid redirects and 404 errors. what can I do to fix the problem.

Try your rules like this:
RewriteEngine On
RewriteRule ^(partnerships/mt4-to-mt4-bridge|platforms/mt4-ecn)/?$ / [L,NC,R=301]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ public/index.php [L]
