Troubleshoot a WordPress install

If activating Klyna throws a fatal error or the admin pages do not render, walk through these in order.

Check PHP version

Klyna requires PHP 8.1 or newer. From your host’s control panel or via SSH:

php -v

If you are on PHP 7.4 or 8.0, upgrade before re-activating. Most hosts have a one-click switcher.

Check WordPress version

wp core version

WordPress 6.4 or newer is required. The block editor uses APIs that did not exist in 6.3.

Re-upload after a partial install

If the zip upload was interrupted, the plugin folder may be incomplete. Deactivate, delete via FTP from wp-content/plugins/klyna, and re-upload.

Admin React panel is blank

Open the browser console. If you see klynaBoot is not defined, your host is caching old asset URLs. Bump the plugin version and hard-reload, or clear the host cache.

Editor sidebar icon missing

The sidebar bundle externalizes React to wp.element. If you have another plugin that loads its own React in the editor, you may see a hook collision. Disable other editor extensions one at a time to find the conflict, then report it via Contact.
