1. ‘.htaccess’ issue –
# Don’t show directory listings for URLs which map to a directory.
I’ve commented the above code in the .htaccess file and all started working fine.
2. Apache web server issue –
Also, if you’re running your website on Apache web server then please make sure the ‘Indexes default‘ option is checked.
You can check that from WHM >> Service Configuration »Apache Configuration »Global Configuration >> Directory “/” Options >> Indexes default
It fixed my issue!
