How to disable .htacess access for a particular account/domain ?

You can disable .htaccess for a particular domain by editing the /etc/httpd/conf/httpd.conf file & following the below mentioned steps:

Open the /etc/httpd/conf/httpd.conf file.
Search for the “AllowOverride None” string.

<Directory “/”>
AllowOverride None
</Directory>

Append it by:

<Directory “/home/username/public_html”>
AllowOverride None
</Directory>

Such that it looks like:

<Directory “/”>
AllowOverride None
</Directory>

<Directory “/home/username/public_html”>
AllowOverride None
</Directory>

Restart the httpd/apache service on the server

This would disable the .htaccess for that particular account/domain.
