I have a website (https://hypermotions.com) which shows directory listing in some browsers only (such as iOS Chrome App), but most desktop & mobile browsers are able to display the website correctly.
What makes the Apache server having such behavior? The website is built using https://imcreator.com, but sure if it's related (thus I have no control on the files, such as .htaccess
).
You can modify the site apache config:
I hope this fixes your issue.
