# ReCaptcha not working – JavaScript Error

 * Hello, we are currently not able to use the reCaptcha integration because of 
   a Javascript Error / Warning:
 *     ```wp-block-code
       reCAPTCHA couldn't find user-provided function: rtecRecaptchaCallback
       ```
   
 * This is probably because the callback funciton is not initialized when the recaptcha
   library tries to pick it up? This causes the recaptcha to stay hidden and probably
   not work properly.
 * Could you help us with that?
 * Thanks in advance and kind regards!
 * Jonas

 * Hey Jonas,
   Sure thing! I have a fix I think will work. I’m testing it and will
   push out a release in a day or two if it looks good.
