What causes 404 errors that forces you to rebuild a .htaccess file? Some css files were leading to 404, a theme change was done recently and I did a git clone of the project and composed up a new docker instance for it. When I tried to browse the website, I had 404 every time I clicked on the css files. What causes this to happen? I am trying to understand why this is happening. I had to rename the old .htaccess file to make it work again. Regenerating the htaccess files from the admin panel tools > redirection, didn’t work.
