Re: I can’t ping my website
You can usually ping your website such as “ping mydomain.com’ which will reveal the IP address of your site and that the server is responding.
Unfortunately this can also be used by hackers to find potentially hackable sites and servers.
For this reason our firewalls block all ICMP PING requests.
Multi-domain web hosting
Each domain can have its own website, files, email addresses, SSL certificate and databases, while all sites share the storage and other limits of one hosting account. It is useful when one person or business manages several modest websites from one Plesk control panel.
Add and manage permitted websites from Websites & Domains. Each domain has its own document root and settings.
A domain can use Sitejet, WordPress or uploaded files without displaying the content of another domain.
All domains draw from the same plan allowance. A busy or badly configured site can affect the capacity available to the others.
Configure SSL, PHP, databases, mailboxes and DNS per domain where the plan and service permit it.
| Plan | Website capacity | Typical fit |
|---|---|---|
| Micro Web+SSL | 1 website | One small website, landing page or test project |
| Basic Web+SSL | Up to 3 websites | A main website plus a few small projects |
| Professional Web+SSL | Up to 15 websites | Several business or client-managed sites |
| Unlimited Web+SSL | Unlimited websites, subject to account limits and fair use | A larger collection of websites managed in one account |
Plan features and prices can change. Use the live hosting comparison and checkout as the current source of truth.
You own the sites, want one control panel and can sensibly share one plan’s storage and resources.
Different customers need isolated access, billing or risk boundaries, or one site is business-critical and resource-heavy.
Keep every application, theme and plugin updated. One compromised login or application can create risk for the account.
Use Plesk Backup Manager and keep suitable copies. UKC also takes daily server-side backups for recovery requests.
Confirm that another website slot and enough storage are available.
Sign in to Plesk on your assigned UKC server and choose Add Domain.
Use the nameservers or DNS records shown for your hosting service.
Publish with Sitejet, WordPress or files, then enable a valid SSL certificate and test email if used.
No. The domains are normally managed within the same Plesk subscription and login.
Yes, subject to the plan’s mailbox allowance. Create addresses beneath the correct domain in Plesk.
Sitejet is included with UKC shared hosting. Availability for a particular site is shown in its Plesk tools.
Yes. If you need more website slots, storage or mailboxes, review the current plans or ask support about an upgrade.
Host more than one website
Allow room for files, databases, email and future growth, not just the number of domain names.
Some applications require open_basedir to be “loosened” a little, if you are installing an application such as ClickCart Pro then the open_basedir will need to be changed so that the installation can create the required sub directories and then complete.
Let’s assume your domain name is domain.com (no such luck, I know!)
# vi /var/www/vhosts/domain.com/vhost.conf
Add the following lines:
<Directory /var/www/vhosts/domain.com/httpdocs>
php_admin_value open_basedir “/var/www/vhosts/domain.com”
php_admin_flag safe_mode off
</Directory>
Now we need to rebuild the apache configuration:
# /usr/local/psa/admin/sbin/websrvmng -u –vhost-name=domain.com
Job done, your open_basdir setting has been moved up one level (from /httpdocs to /) within your domain name sub folder.
WordPress troubleshooting
The common causes are incorrect ownership or permissions, insufficient disk space, a security block or files left by a previous manual upload. Back up the site before changing anything.
The path tells you which folder WordPress could not write to. An uploads error, plugin update and core update can have different causes, so keep the complete message.
Open Plesk resource usage and confirm the subscription has enough space for an extracted update and temporary files.
Use Plesk file tools or ask UKC to repair ownership. Typical permissions alone do not fix a file owned by the wrong system user.
Imunify or another security layer can block a suspicious write. Record the time and file so support can investigate safely.
If an update stopped unexpectedly, confirm the site is not left in maintenance mode before trying again.
Create a Plesk backup or confirm a usable restore point.
Complete one operation, then check the front end and admin area.
Work in small batches so a failure can be identified.
Open a ticket if Plesk reports a full subscription, ownership appears wrong, the same path repeatedly fails, or a server security rule may be involved. Include the domain, exact error, affected path and time. Do not include passwords.
Next step
Send the exact error and affected path so UKC can check the account safely.
As you are reading this, you are probably unaware of how easy it really is to install a web application such as WordPress. It really is just a few button clicks with Plesk.
Ok, so there are 15 items in the list – really, it would have taken you longer to read the list than to install WordPress. Install WordPress now and see how easy it is, you can just delete it afterwards – and that’s just as easy as pressing one button!
