Addon Domain :: Addon domains can be added to your hosting account as an upgrade. They allow you to have more than one independent website sharing the resources of your hosting account.

[ consider your addon domain name as addondomain.com ]
There are 3 ways of accessing an addon domain:
1. addondomain.com
2. main-domain.com/addondomain
3. addondomain.main-domain.com

Parked Domain :: A parked domain is one which simply points to an existing domain. It is an other domain which is parked on to the main domain. Consider a domain “parked.com” which is parked on the “main-domain.com”. If we access parked.com it will be directed to the main-domain.com and you will get the same page as you see while accessing main-domain.com. The parked domain should also point to the same nameservers as the main-domain.com. The park domain name should be registered.

Make sure the Name servers for the othersite.com (addon OR parked) has the same Name servers registered that of main site.

If you receive such error in the error logs OR in the browser make sure output_buffering is set to On in the php.ini file on the server.

If you are on a su-exec/su-php enabled server, copy the original php.ini from the server under the account and make the changes.

What is output_buffering ?

Output buffering allows you to send header lines (including cookies) even
after you send body content, at the price of slowing PHP’s output layer a
bit.  You can enable output buffering during runtime by calling the output
buffering functions.  You can also enable output buffering for all files by
setting this directive to On.  If you wish to limit the size of the buffer
to a certain size – you can use a maximum number of bytes instead of ‘On’, as
a value for this directive (e.g., output_buffering=4096).

What if you want to generate the account backup without the home diretcory ?

Here is the command to exclude/skip home diretcory

root@server [~]# /scripts/pkgacct –skiphomedir username

Note :: Here username is  actual cPanel username.

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.
