It’s back up now. Thanks.
I’m now able to access my dashboard, due to adding the following as a custom permalink: /%year%/%postname%/
However, my links for pages 2 and 3 still don’t work.
Now I can’t access my dashboard on the site. It directs me to the following page: 4starlist.com/dashboard/
I’ve tried changing the permalinks back to the default settings and it still doesn’t work.
