How to Install a phpBB Forum
phpBB is one of the most widely used open-source forum systems. OpenPanel installs a ready-to-use board in one click, with backups and cloning built in.
Requirements​
- OpenPanel Community or Enterprise - the phpBB module must be enabled for your hosting plan.
- A domain or subdomain, e.g.
forum.example.com. - A PHP version supported by your phpBB release.
Install phpBB​
- Add the domain in OpenPanel → Domains (Add a new domain).
- Go to OpenPanel → Websites → Install App and click Install phpBB.
- Fill in the domain, phpBB version (Latest), board name and description, and the admin username, password and email.
- Start the installation.

OpenPanel downloads the official release, creates a MySQL/MariaDB database, runs phpBB's CLI installer and removes the install/ folder.
Open https://forum.example.com and log in with the admin account. The Admin Control Panel (ACP) link is at the bottom of every page.
First Steps After Installing​
Stop spam registrations​
New forums attract spam bots quickly. In ACP → General → Board configuration → Spambot countermeasures, enable a CAPTCHA plugin (reCAPTCHA or Q&A) and set User registration → Account activation to By user (email verification) or By admin.
Configure email​
phpBB sends activation and notification emails. In ACP → General → Client communication → Email settings, enable SMTP and enter a mailbox from your domain. See Why do my emails go to spam?.
Board settings​
In ACP → General → Board settings, set your time zone, default language and board style. Install extra language packs and styles from phpbb.com.
Updating phpBB​
phpBB doesn't have a safe automatic CLI updater, so updates are done from the forum itself:
- Create a backup from the forum's manage page in OpenPanel.
- The manage page's Update tab shows the installed version and opens the ACP.
- In ACP → System → Automation, follow phpBB's update procedure with the Automatic Update Package.
Managing the Forum​
The manage page in OpenPanel → Websites → Sites has:
- Backups - database, files or both, with one-click restore.
- Clone - copy the board to another domain, e.g. to test an update or new style.
- Update - installed version and a shortcut to the ACP.
- Remove - uninstalls the forum and its database.
