Free Upgrade to Admin Columns Pro
The Pro Add-on, which supplies additional features in Admin Columns, is deprecated and no longer supported by Admin Columns version 2.2 and higher. The Pro Add-on is replaced by Admin Columns Pro, an advanced version of Admin Columns featuring sorting, filtering, direct inline editing, import/export functionality and much more.
If you’ve purchased a license of the Pro Add-on, you get a free license of Admin Columns Pro that matches to your current Pro Add-on license. This includes 1 year of free upgrades and support. If you’ve previously purchased the Unlimited license for the pro add-on you also get access to all external plugin integration add-ons like the the Advanced Custom Fields (ACF) add-on.
Go to your account, download and install Admin Columns Pro in your existing installation and it will keep all your current settings. The installation will deactivate the Pro Add-on and Admin Columns for you, as they are no longer required. Continue where you left off, but with more features.
