@fffddd-dfeeedd Yes, nodebb-plugin-customize which will allow you to change templates etc.
i need to add the code into the startup file ,such as index.html ,or index.php
i cannot find such file as index.×xx, would you someone help to know which is the website first page ?
NodeBB isn't like PHP. It doesn't work like that. What do you want to change / add?
This is all dependent on how each server is configured.
