How to run version 4 in a subdirectory

Hi, take a look at this tutorial:
https://forum.codeigniter.com/thread-76777.html

And instead of /public_html/ it should be /public_html/edit

And you need ../../ instead of ../ in your index.php file.

If it dosen't work, open up your .htaccess and only change "RewriteBase /edit", everything else should be left as is.
