Thanks for the replied.
I keep this useful info.
-At first, I clicked on "service" ,
-Then clicked on httpd button ( service started at boot for httpd ),
-It runs fine, but seems like no stable.
I restarted the VPS, then could not login to KloxoMr.
As usual, run commands:
#sh /script/cleanup
#sh /script/fix-all
#sh /script/restart-all
#reboot
Able to login KloxoMr again. Surprisingly, it also auto-disables Hiawatha...
Now, the domain appears as normal.
Thank you for attention
