Problem with setting Rewrite Directives

Hi,

I seem to be having some trouble with Apache Rewrite Directives.

I put the following directives inside of my /etc/apache2/sites-available/default file:

RewriteEngine on RewriteCond %{request_filename} -f RewriteRule ^(.) $1 [L] RewriteRule ^(([^/])+)(/([^/]{0,32})(/.+)?)?$ index.php?a=$1&q=$3 [L]

When I did that they worked just the way I intended. Except that everytime I navigated to the phpmyadmin url I’d get a 500 error.

So to solve this I added RewriteRule ^(phpmyadmin)($|/) - [L]

However when I did that it seemed to have the effect of completely turning the rewrite engine off.

This is the complete config for the directory

"<Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all RewriteEngine on RewriteCond %{request_filename} -f RewriteRule ^(?:phpmyadmin)($|/) - [L] RewriteRule ^(.) $1 [L] RewriteRule ^(([^/])+)(/([^/]{0,32})(/.+)?)?$ index.php?a=$1&q=$3 [L]

</Directory>"

Any help would be appreciated.
