Now site is available. jkhongusc, you can check it.
I think problem in the other place. If it caused by .htacces file, it doesn’t work all time, but my site works on the hosting. Thanks for help, may be you have more ideas?
This hosting use branch – ngnix for static content, apache for dynamic content. My site work, but when you start to use them, infinity loop request crashed server, then frontpage became blank and other pages gives 404 error.
