webpage shows nothing

I visited the link you posted, and it gives me an error, which says a function is not defined.
What exactly do you want to do?
What exactly have you done so far?

cos l originally installed WP under the default “wordpress” ,and my blog can be only seen at the url of :https://kelet.512j.com/wordpress
but i want the https://kelet.512j.com to be my blog url
so i re-installed wp under my server root,but i can login into the management,but can’t see my blog
i don’t know why?

Fixing these may help: https://validator.w3.org/check?uri=http%3A%2F%2Fkelet.512j.com%2F

I’ve done it .Thanks a lot
cos i did’t activate the style-switch in my plugins.
Now it works.Thanks again:))

Now you need to adjust the link in your preferences here.
