Wampserver loglevel rewrite not working - .htaccess

Question

I am using WampServer and I would like to debug my rewrite rules from .htaccess, since I still receive 404 errors.
I already enabled rewrite_module, log_debug_module, log_forensic_module and log_config_module, but in my error log I don't receive any information about .htaccess.
In httpd.conf I changed LogLevelto: LogLevel warn mod_rewrite.c:trace8. I also tried the following options: rewrite_module, mod_rewrite.so, rewrite, mod_rewrite.
Then when I restart the server I only get this log, but I don't receive anything about web requests when I try to go to localhost/mysite.

UPDATE
Here is some more information about my folder structure. I have put my DirectoryRoot to D:/www and my .htaccess file is in D:/www/mysite.
Some parts from httpd.conf:
<Directory />
AllowOverride none
Require all granted
</Directory>
DocumentRoot "D:/www"
<Directory "D:/wamp/www">
Options Indexes FollowSymLinks
AllowOverride All
# Require all granted
# onlineoffline tag - don't remove
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from ::1
Allow from localhost
</Directory>
#ErrorLog "logs/error.log"
ErrorLog "c:/wamp/logs/apache_error.log"
#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
#
LogLevel warn rewrite:trace3
Disabling the rewritemodule gives errors on RewriteEngine so I suppose that it does find my .htaccess file.
This is my .htaccess file:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*?)/?$ index.php/$1

Answer 1

Could it be that you are using Apache 2.4.x, if so they have made major changes in the area of logging.
Try
LogLevel alert rewrite:trace3
Also another change is that logged info gets written to the normal error_log file.
Documentation
ADDED After Additional Info added
You have some fairly obvious errors in your httpd.conf file.
Can I suggest you review this document on the WAMPServer forum Wampserver 2.4 What to do after Installing
I just changed my WAMPServer Apache conf as so:
LogLevel warn rewrite:trace8
And got lots of extra lines in my apache_error.log from the rewrite module.
Make sure you are actually running something on the server that will exercise mod_rewrite and the RewriteRule you have in your .htaccess

Answer 2

After editting yor 'httpd.conf' log to
LogLevel alert rewrite:trace3
You should restart apache server to apply changes.
