I have done everything you have mention in comments, but haven’t get any success yet.
I have reset .htaccess file , and already added php.ini file in the root folder. Even i have renamed plugins folder too but nothing happened in sub domains.
My sub folders and other pages are working fine as you can see these links which i have mention below.
but multi sites are set un sub domains which are not working, even their dashboard is not working either.
Please suggest, what should i do to solve this issue?
Awaiting to hear from you..
