It’s been a long time coming, but OIO Publisher v3.0 is finally here — rebuilt, refreshed, and ready for today’s WordPress environment.

For years, OIO has been the go-to self-hosted ad manager for website owners who want to take full control of their ad sales. With this new version, we’ve focused on making OIO easier to use, faster to load, and fully compatible with modern WordPress and PHP versions — while keeping the same core principle that made it popular in the first place: you control your ad revenue, not middlemen.

What’s New in OIO v3.0

This update isn’t just about bug fixes — it’s a complete modernization of the plugin’s foundation. Here’s a quick look at what’s new:

  • Full PHP 8+ Compatibility: The codebase has been cleaned up and updated to run smoothly on all modern PHP environments, ensuring long-term stability.
  • New Interface: A cleaner, more professional design throughout the admin area for a better user experience.
  • Shortcodes & Purchase Pages Fixed: Shortcodes now work properly out of the box, and purchase pages have been fully restored and improved.
  • Improved Performance: Faster load times, better caching, and more reliable ad serving.
  • Better Email Handling: Notifications and order confirmations are now more consistent and compatible with major hosting environments.

This release was built to ensure that longtime users can continue using OIO for years to come — with a focus on simplicity, speed, and security.

Built for Publishers Who Want Control

Unlike most ad networks, OIO lets you sell your own ad space directly to advertisers. That means no commissions, no platform restrictions, and no third-party tracking taking a cut. You own the data, the design, and the revenue.

With OIO v3.0, setting up ad zones and managing campaigns is faster and smoother than ever. Whether you’re selling banner ads, text ads, or custom placements, everything is handled from your WordPress dashboard.

Why This Update Matters

A lot has changed in the ad landscape since OIO first launched — but one thing hasn’t: website owners still want control over their income.

This version represents a renewed commitment to that goal. OIO is now fully compatible with modern WordPress setups and can easily integrate into your existing workflow.

If you’ve been waiting to reinstall OIO or migrate your ad setup from third-party platforms, now’s the perfect time to do it.
