Do you have any plugins that work with or modify WooCommerce? Have you tried installing the [WordPress Health Check Plugin](https://wordpress.org/plugins/health-check/) and following [their documentation](https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/) you should be able to safely disable all plugins except Contact Form 7 and reCaptcha v2 for Contact Form 7 as well as switching to a default theme. This will ensure there’s no plugin or theme conflicts preventing the plugin from working properly. * [Rob](https://wordpress.org/support/users/rob70/) * (@rob70) * [5 years, 8 months ago](https://wordpress.org/support/topic/recaptcha-api-javascript-error/#post-13434244) * Hi josephuspaye * I delete my comment, the above message you have to answer, sorry * [reCaptcha screen copy](https://rvwing.synology.me/drive/d/s/577383262394036585/_kkttCrNNKPV1UuNTnzz3ah_cQ15vrdE-GbJAVe1KAwg_) * Success, Robert (PL) - This reply was modified 5 years, 8 months ago by [Rob](https://wordpress.org/support/users/rob70/). - This reply was modified 5 years, 8 months ago by [Rob](https://wordpress.org/support/users/rob70/). - This reply was modified 5 years, 8 months ago by [Rob](https://wordpress.org/support/users/rob70/). - This reply was modified 5 years, 8 months ago by [Rob](https://wordpress.org/support/users/rob70/). - This reply was modified 5 years, 8 months ago by [Rob](https://wordpress.org/support/users/rob70/).
