I have installed but get this error
Your hosting is not compatible with default EPESI root .htaccess file. You should tweak it yourself.
Default .htaccess file is:

Options -Indexes
#SecFilterEngine Off

#if your server is running php as apache module:
php_value memory_limit "64M"
php_flag magic_quotes_gpc off

#if your server is running php as cgi/fastcgi you should set following directive instead of above php_value/flag
#SetEnv PHPRC /your/epesi/root/directory/php.ini

RedirectMatch 404 /\\.svn(/|$)
RedirectMatch 404 /\\.git(/|$)

relating to the install, it is not clear EXACTLY what needs to be done?
Should I copy and paste this to the htaccess file

I looked at the past posts but can also not be sure what is to be done, please advise step by step what needs to be done
