Could you please help me ? It was working yesterday… * Thank you * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fotp-code-always-incorrect%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 3 replies - 1 through 3 (of 3 total) * Plugin Author [gaurav1092](https://wordpress.org/support/users/gaurav1092/) * (@gaurav1092) * [11 months, 1 week ago](https://wordpress.org/support/topic/otp-code-always-incorrect/#post-18530968) * Hi [@ilyena](https://wordpress.org/support/users/ilyena/), * It’s possible that a recent plugin update or conflict is causing the OTP to fail. * Please try deactivating all other plugins except **Customer Email Verification for WooCommerce** and **WooCommerce**, then test the OTP again. * Also, the page you mentioned — `/login-authentication/` — is not part of the ** Free** version of the plugin. Could you confirm if you’re using the **PRO** version or the **Free** version? * Thanks * Thread Starter [ilyena](https://wordpress.org/support/users/ilyena/) * (@ilyena) * [11 months, 1 week ago](https://wordpress.org/support/topic/otp-code-always-incorrect/#post-18531514) * Hello [@gaurav1092](https://wordpress.org/support/users/gaurav1092/), * There were updates yesterday, but I was able to login after they installed. It’s even worse after deactivating all other plugins: I don’t receive the OTP email, and when I click on Try again, I get the error below. * I’m using the PRO version, and not using the popup.
