Upgrade to Pro

Pro is installed over the free version. You don’t uninstall Free first, and you lose nothing: your scans, open problems, waiting suggestions, History and Options, including your AI key, all stay.

Installing Pro

Buy a plan on the JS Accessibility Fixer page. The order email and your order page on joomsky.com show your licence key.
On joomsky.com, open the order in My account › Orders and press Download Pro next to your key. You get pkg_jsaiaccessibilitypro-<version>.zip.
In your Joomla administrator, go to System → Install → Extensions, and upload the Pro zip on the Upload Package File tab, the same way as Free.
Go to Components → JS Accessibility Fixer. The dashboard now has the Pro rows, and the menu has Statement, Client report and Licence.
Enter your licence key on the Licence screen, so you get updates. See Licence key.

What the Pro install does

It updates the component and the content plugin, and adds two plugins: Task - JS Accessibility Fixer (monthly scan and nightly suggestions) and Installer - JS Accessibility Fixer (Pro updates). It turns them on.
It takes over from the free package. In System → Manage → Extensions you see JS Accessibility Fixer Pro instead of the free package, and Joomla looks for Pro updates instead of free ones.
The monthly limit of 50 AI suggestions no longer applies.

Pro works without the key

Every Pro feature works as soon as Pro is installed. The licence key is for updates and support. If you don’t enter it, or the licence ends, Pro keeps working; only new versions stop arriving.

Going back to Free

The free package does not install over Pro. To go back, uninstall Pro under System → Manage → Extensions, then install Free. This removes the scan results and the History; fixes you accepted stay in your content.
