.htaccess gives 500 Internal Error

[J-v-N]

Hello,

I have a very weird problem everything was working fine until a few days ago mysql gave mysql_too_many_connections error so I've rebooted the server after that I started to get 500 Internal Errors

after some digging around I found out that its the .htaccess file if I remove the file it works fine

I've started to check the file if the hole file is remarked "#" it works fine if I get one line out of remark it gives 500 Error

heres the file

RewriteEngine off
##point to installation directory
##if it is the root dir,enter /
##else /otherdir
RewriteBase  /

RewriteCond %{QUERY_STRING} ^d=([a-zA-Z0-9]{8})$
RewriteRule ^$ download.php?id=%1

RewriteCond %{QUERY_STRING} ^d=([a-zA-Z0-9]{12})$
RewriteRule ^$ delete.php?id=%1

RewriteRule   ^file/([0-9]+)/(.*)$ download.php?id=$1&type=2 [L]

RewriteRule   ^top/([0-9]+)\.html$ top.php?s=$1&type=1 [L]

I checked /var/log/apache2/error_log and nothing was there

edit:

Issue solved mod_rewrite wasn't enabled it took me quite some time to figure it that I have to load it from /etc/sysconfig/apache2 but it works now
