If you get a rewrite loop in Plesk 11.5 then make sure you’ve set the Preferred Domain field correctly in the hosting settings.
See this article for details:

This can be especially tricky with WordPress. Make sure the site url in WordPress matches the preferred domain setting.
There’s a cool new feature in Plesk ll.5 that provides a “canonical rewrite rule” that you can turn on off from the panel. To find the setting, login to Plesk, drill down on your domain and go to:
Websites & Domains -> Hosting Settings
Notice the “Preferred domain” field.
There are three options for this field:
“None” – do nothing
“domain.tld” – redirect to remove the www
“www.domain.tld” -redirect to add the www
Just set this field to your preference and Plesk will configure the appropriate rewrite rule in Apache.
It’s easy to setup WordPress in multi-site mode on Plesk.
Let’s assume you want to map:
|
1 |
*.acme.com |
to your multi-site installed on “acme.com”.
From an SSH login on the server, just edit the file:
|
1 |
/var/www/vhosts/domain.tld/conf/vhost.conf |
If the file does not exist then create a new empty file.
Add the following line to the top of the file:
|
1 |
ServerAlias *.domain.tld |
Save the file and tell plesk to reconfigure:
|
1 |
/usr/local/psa/admin/sbin/httpdmng --reconfigure-domain domain.tld |
Now restart Apache:
|
1 |
/sbin/service httpd restart |
Now you’re ready to go with multi-site.
There’s an article here that addresses subdomain and webmail issues:

Here’s the command line steps to add Google Apps to a domain under Plesk:
|
1 2 3 4 5 6 |
/usr/local/psa/bin/dns --add acme.com -mx '' -mailexchanger ASPMX.L.GOOGLE.com -priority 10 /usr/local/psa/bin/dns --add acme.com -mx '' -mailexchanger ALT1.ASPMX.L.GOOGLE.com -priority 20 /usr/local/psa/bin/dns --add acme.com -mx '' -mailexchanger ALT2.ASPMX.L.GOOGLE.com -priority 20 /usr/local/psa/bin/dns --add acme.com -mx '' -mailexchanger ASPMX2.GOOGLEMAIL.com. -priority 30 /usr/local/psa/bin/dns --add acme.com -mx '' -mailexchanger ASPMX3.GOOGLEMAIL.com. -priority 30 /usr/local/psa/bin/dns --add acme.com -cname 'mail' -canonical ghs.google.com. |
For a server using Plesk add the following lines to a .htaccess file to stop execution of PHP scripts in the folder:
|
1 2 3 |
RemoveHandler .php .phtml .php3 RemoveType .php .phtml .php3 php_flag engine off |
I like to use this to protect cache and image upload folders that are writable by the web server but should not be able to execute code.
As a further precaution, chown the .htaccess to root, so it can’t be overwritten by Apache or FTP, and “chattr +i” to be sure about it.
