Activating

Installing

• In the suite, Pixel comes with the suite’s Pro plugin. Activate the suite first, then its Pro plugin on the Plugins screen; Pixel then appears in the workspace sidebar.
• The standalone SleekPixel plugin is installed like any plugin and adds Pixel to the SleekWP menu.

Pixel needs the Imagick PHP extension to render images; see Troubleshooting.

The license

The license connects the site to SleekWP’s store; the standalone SleekPixel plugin uses it to receive updates. Pixel’s images, rendering and settings work whether or not a license is active.

On the License page

Open Pixel’s License page: in the suite it sits beside Pixel’s Settings in the workspace sidebar, and in the standalone plugin in Pixel’s own navigation.

1. Enter the license key.
2. Activate it.

The page asks the store to activate the key for this site and shows the result as valid or invalid. Only a valid key is kept; an invalid one is discarded. Deactivating asks the store to release the key for this site and removes it, together with its status.

The page is hidden when the standalone plugin is white-labelled.

With a constant

You can provide the key in PHP instead, for example in wp-config.php:

define( 'SLEEK_PIXEL_LICENSE', 'YOUR LICENSE KEY' );

While the constant holds a non-empty key, the License page shows that key, masked, as managed by the constant, and refuses to activate or deactivate a key entered on the page. The constant does not activate the key with the store by itself.

Updating from an earlier SleekPixel

Images, custom fonts, settings, the Google Fonts key and the license stay where earlier versions stored them. The first request after an update that changes how rendered files are named deletes the old files once, and every image renders again on its next request. The assistant replaces the earlier built-in AI chat; the AI keys that chat kept move to the AI settings once, for each provider that has no key there yet.

Uninstalling

Deleting the plugin removes the tables the earlier built-in AI chat used, Pixel’s version markers, the Agent Sync markers on the image designs and the queue of background renders with its scheduled check, on every site of a network. Deactivating it removes the scheduled check and keeps the queue. It keeps the image designs, custom fonts, settings, the Google Fonts key, the license, the design files Agent Sync wrote to the theme and the rendered files under wp-content/uploads/sleek-pixel, so reinstalling Pixel finds them again.

While another plugin that carries Pixel is still installed, such as the suite’s Pro plugin after you delete the standalone SleekPixel plugin, Pixel’s data stays for it and deleting removes nothing.
