Hi everyone,

We start using Sharepoint 365 (online). We used to work with Sharepoint Server 2019 (on-premise) version.

Using classic interface, we tried to customize navigation of Sharepoint with CSS code but could not find Script Editor webpart in menu. Using custom script options were already enabled in Sharepoint Admin Center. We don't plan to use modern interface for now.

Does anyone know how to fix that issue or another method to do?

Thanks in advanced.

    Hi @mountaineer2007 ,

    Welcome to Q&A forum!

    In addition to allowing Custom Script at the tenant level, you also need to allow it at the site level.

    Tenant level:User's image

    Site level:

    User's image

    The result:

    User's image

    Please note:

    By default, any changes to custom script settings for a specific site only last for a maximum of 24 hours. After that time, the setting will reset to its original value for that specific site.

    This may cause some trouble for you.

    For more information, please refer to:

    https://learn.microsoft.com/en-us/sharepoint/allow-or-prevent-custom-script#allow-or-prevent-custom-script

    For a better user experience, you can try to explore creating custom solutions using SharePoint Framework, which is designed for modern experience. Although it is different from your usage preferences, it is a good choice.

    Good day!
