Upgrading from 3.2 to 3.3
Upgrading to phpBB 3.3 may cause some styles and extensions to no longer work. If you have a custom logo, it might need to be redone after the upgrade. See Knowledge Base: How to Change your Board Logo.
phpBB 3.3 should be backwards compatible with 3.2, however some extensions and custom edits may no longer work. The easiest upgrade method is to remove all existing files prior to upgrading and re-applying custom changes after verifying their correctness.
To upgrade, perform the following steps:
Ensure that your server meets the requirements for running phpBB 3.3: Section 1.1, “Requirements”
Make a backup of the original files
Make a backup of the database
Deactivate all styles except for prosilver
Deactivate any extensions which are not compatible with phpBB 3.3. Check with the extension author to find out if an extension is compatible or not.
Set British English as the only language pack
Download the phpBB 3.3 Full Package archive
Extract the contents of the archive to your computer and open the phpBB3 directory
Delete the following files from the package:
The config.php file
The files/ directory
The images/ directory
The store/ directory
On your website, delete all files from your board EXCEPT for:
The config.php file
The ext/ directory
The files/ directory
The images/ directory
The store/ directory
Upload the contents of the phpBB3 directory from your computer to your forum's directory. You may be prompted to overwrite the remaining files. If prompted to merge or overwrite directories, choose to merge them.
Update the database:
Tip
For large boards, you may wish to update via the command line instead of using a web browser. From your board's root, execute the following command:
php ./bin/phpbbcli.php db:migrate --safe-mode
Using your web browser, visit install/ in your board's root. (e.g. http://www.example.com/yourforum/install)
Click the Update tab
Click the Update button
Select "Update database only" and click Submit
Wait for the progress bar to reach 100% and for a message indicating that the update has completed
Delete the install/ directory
Note
Ensure that the root level .htaccess file is included in the upload. Some FTP clients do not show files whose names start with a period and you may need to enable the display of hidden files.
Note
If your board made use of language packs other than British English, you will need to download a version that is compatible with phpBB 3.3 from https://www.phpbb.com/languages/
Important
When uploading the 3.3 files to your server, do NOT overwrite your config.php.
Important
When backing up your files, ensure that your FTP client is in binary mode or transfers files without extensions in binary mode.
