Each WordPress website installation comes with the WP IDE File editor plugin to edit and update WordPress site files.
Why Don’t I have FTP?
Due to the dockerized nature of WordPress sites on FluxRunner, the files are not directly accessible via FTP. We are working on extending the file editing capabilities via FTP.
How to edit files
Once you are in WP Admin, head on over to WP IDE section and you will be able to access your WordPress installation folder and files.
