we have installed recaptcha and woocomerce and wp security. When registering on the site, all you have to do is enter the e-mail address and the account is created automatically but we had more than 150 fake accounts so the captcha does not work on your theme.
Please make the full backup of your site as well as the Theme settings export and check the issue on the Storefront theme to detect if our theme causes the problem. Storefront is a free theme developed by WooСommerce.
