So I installed wordpress but when someone wants to acces my site he needs to write /wp at the end, can I change it so it is without the extra /wp at the end
Apparently WordPress was installed in a directory (/wp) and that's why you need to write the name of the directory at the end. To fix it you have two options:
1. You install WordPress again, taking care not to install it in a directory (again).
2. Use a redirection that allows users to visit the main page and be redirected to the current directory (/wp).
