I am not able to access website subdomains after I made some changes on the root directory (public_html). All are generating “500 server error”. Probably the problem is because of .htaccess file content. The subdomains works fine when I remove the .htaccess file content. But this can’t be solution for my problem because it is important for my website. The root directory .htaccess file content looks like this
Options +FollowSymLinks
RewriteEngine On
AddEncoding gzip .gz
AddEncoding gzip .gzip
<FilesMatch "\.(js.gz|js.gzip)$">
ForceType text/javascript
</FilesMatch>
<FilesMatch "\.(css.gz|css.gzip)$">
ForceType text/css
</FilesMatch>

RewriteCond %{REQUEST_URI} .*/http-bind
RewriteCond %{REQUEST_URI} !/ow_cron/run.php
RewriteRule (.*) /http-bind [L]

RewriteCond %{REQUEST_URI} !^/index\.php
RewriteCond %{REQUEST_URI} !/ow_updates/index\.php
RewriteCond %{REQUEST_URI} !/ow_updates/
RewriteCond %{REQUEST_URI} !/ow_cron/run\.php
RewriteCond %{REQUEST_URI} (/|\.php|\.html|\.htm|\.feed|robots\.txt|\.raw|/[^.]*)$ [NC]
RewriteRule (.*) index.php

Anyone who can give me suggestion to fix the problem of accessing the subdomains?
Thanks
