Currently, when I create any new website, the index.html file is Default Website Page. I want to change it to be index.php automatically. When I create any new website, index.php is added instead of index.html.

I tried a lot for more than 24 hours

1- I have /usr/local/CyberCP/index.html

I changed to /usr/local/CyberCP/index.php but it didn’t work

2-I also tried changing it in the LiteSpeed ​​WebAdmin Console

cd. dmain-host. com:7080

Index Files index.php
But it didn’t work either

I want the individual file to be index.php, I do not want it to be index.html
If you could please help me
