phpBB Extensions Extensions

Manually editing code is a thing of the past. Quickly installed in the ACP, extensions are to phpBB 3.1 what MODs were to phpBB 2.0 & 3.0. Our huge customisation community is hard at work building new extensions to help you get the most out of your forum.

PHPBB SecurityUnmatched Security

Nothing is more important than keeping your data safe, and our record speaks for itself. In the past four years, there have been no reported vulnerabilities in the phpBB software. Meanwhile SMF, vBulletin, IPB, and MyBB have had an average of 10, and as many as 16. That's an average of 10 more reasons to choose phpBB. And just to make sure, we hired a professional security company to audit the entire phpBB 3.1 codebase.

Version Check Simplified Updating

If you're tired of complicated updating procedures, you'll love phpBB 3.1. Whether it's extensions or phpBB itself, updating is as simple as uploading the new package and clicking a few buttons. You can even check to make sure you're running the latest versions, right in the ACP.

Features, changes and improvements


Traditionally with phpBB, even simple operations like deleting a post or reordering forums have involved multiple requests and full page loads, which was slow and heavy on bandwidth. We've added AJAX functionality to a lot of these simple operations, making them faster and easier to do.

Improved Style Inheritance Improved Style Inheritance

The templating system has been completely overhauled. The folder structure has been cleaned up, providing an increased ability to inherit from the other styles. No more unnecessary and confusing configuration files!
