Plesk: After upgrade to Plesk 10, www prefix is not working anymore


Since Plesk 10.x the domain-handling is changed, if your Apache configuration is not configured correctly the default plesk page will be shown when you browse to your domain with the www prefix.

The resolution for this problem is that you have to add a CNAME record and reconfigure the Apache configuration for your domain(s). I will use domain ‘how2forge.info’ as example.

1. Add the correct CNAME record

1a. Login to Plesk Control Panel as user, not as admin.
1b. Go to Websites & Domains.
1c. Click on DNS Settings.
1d. Click on Add Record.

Record type: CNAME
Domain name: www.how2forge.info.
Canonical name: how2forge.info.

Click on OK to save the record.

Now you have to log in via SSH on to your server and reconfigure the Apache configuration for your domain:

# /usr/local/psa/admin/sbin/httpdmng –reconfigure-domain how2forge.info
(please note the double ‘-‘ before reconfigure-domain, wordpress is removing the double dashes)

Done! Your website should now be accessible with the www prefix.

If this have not solved the problem, probably you still have an A record for www.how2forge.info. Remove the A record and it should work.

Good luck!
