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.

    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.

    Use open source media player (e.g. ) and add a playlist feature for the end user similar to Playlist feature on Youtube where anyone can create multiple playlists from content available. In this case, content would be come from a single hosted video library. I, as the admin, would also need to created playlists for the end user as an easy way to get them started. Videos must autoplay to the next video automatically and the video box must remain full size from one video to the next. In many cases, once a video is completed it returns to the home page where the video appears at the original size. I do not want this to happen.
