Backend Development Jobs

Backend code is the part of a website or application that isn’t visible to the user. The code is a behind-the-scenes part of development, requiring a high level of competency regarding coding and the server that is being used. A backend developer works on the implementation and configuration of systems, and thus provides the building blogs for a website or program.

    Queremos desarrollar una plataforma de suscripción a contenido exclusivo para un nicho en específico, en donde los creadores de contenido se registren y puedan publicar material, el cual puedan ver solamente las personas que estén pagando su suscripción mensual. Los creadores reciben el pago de acuerdo a la cantidad de personas suscritas a su contenido y la plataforma, un porcentaje de ello. Es un modelo de negocio muy común hoy en día y ya existen plataformas muy grandes como OnlyFans y Patreon. Este proyecto es para un nicho en específico y no será de contenido explícito. Necesitamos alguien que pueda llevarlo a cabo y nos platique todos los requerimientos para estar en línea y completamente funcional.

    Hi I am using a readymade script on my website. I was customising the website as per my requirements. As soon as I clicked on enable reCAPTCHA v3, I got accidently logged out from the website and couldn't login again a getting error when trying to log in, when forgetting the password or even creating a new user. Screenshot attached! I think I have to disable the reCAPTCHA v3 through other method such as Cpanel or PHPmyadmin? Any idea how we can disable the reCAPTCHA v3 without log in to the website backend as it is not allowing to login.
