I just realized
first nineteen domains work on this VPS. But not work more.

Do one thing.
Go to modify domain and switch back to different version.
Now refresh the website.
Again switch back them to original php version.
It may solve the issue

@bijay thank you
but unfortunately
the problem continues

Message me so that i can have a check the exact issue. @sertsidk

i think ; i find my error just now.

httpd_config.conf file damaged over time and I think working with multiple domains contributes to this. Because I have encountered this problem more than once.but others don’t have the same problem
i use 50 or 60 mixed domain or subdomain on my vps. Up to 15-20 no problem. But problem is more use domain or subdomain. there is this text in some parts of the file
“NUL NULNUL NULNUL NULNUL NULNUL NULNUL NULNUL NULNUL NUL”. And; the problem goes away when you delete them

I want it to be known;
this problem started with 2.0 version.

Is there a permanent solution to this?

Not sure if this will work for you but you can try it. Go to file manager then select all files and click fix permission

no;
httpd_config.conf file in /usr/local/lsws/conf folders. Not in home directory.
