# Login Error – Undefined

 * Hi,
 * It appears that the **Ultimate Member – reCAPTCHA** plugin is no longer functioning
   correctly.
 * When the plugin is enabled and reCAPTCHA is turned on in Ultimate Member settings,
   users receive the following error when attempting to log in. If reCAPTCHA is 
   disabled in Ultimate Member or if the reCAPTCHA plugin itself is disabled, login
   works normally.
 * **Error: **“undefined” appears above the login box.

 * Troubleshooting steps already performed:
    - Tested across multiple themes, including default WordPress themes
    - Disabled all other plugins to rule out conflicts
    - Confirmed the issue persists regardless of theme or other plugins
 * Based on these tests, the issue seems isolated to the Ultimate Member – reCAPTCHA
   plugin itself. I also noticed the plugin has not been updated in over a year,
   so it may no longer be compatible with current WordPress or Ultimate Member versions.
 * Please let me know if this is a known issue or if an update is planned.
 * Thank you.
