Extensions
The Extensions tab manages license keys for Oxygen's extension plugins — products like
Breakdance Elements for Oxygen, Breakdance Forms for Oxygen, and Breakdance WooCommerce
for Oxygen. In wp-admin, go to Oxygen → Settings → Extensions.

Each installed and active extension gets its own License Key field. Paste the
extension's key and click Save Changes — Oxygen validates the key and activates it
for this site, then shows the key's status under the field: active, invalid,
inactive, or expired. To remove a key, clear its field and save.
The saved key is masked in the field. When editing, either paste a complete new key or
clear the field entirely — a partially-edited masked value is ignored on save.
If the tab is empty, no extension plugins are installed and active on this site — install
the extension plugin first, and its license field appears here.
