"Not a directory" error w/ Nginx + PHP7

You can delete .css and .js files in your assets folder, and they will regenerate.

I've changed the title so that this thread can be more easily found by others who encounter the same issue.

Please let us know if the suggestion by jordanjay29 fixes the problem!

Can you post your entire nginx config?

Also, please post your config.php from your flarum root directory (cencoring the database password of course)

configuration must often bind not replace
