Solution to the problem that WordPress cannot be opened after "WordPress address (URL)" is modified in the background

At the invitation of a friend, I am going to use Wordpress to build a site.

After the installation is complete,

The "WordPress address (URL)" address is modified in the "general options" setting. After saving the address, the backend cannot enter...

I also checked the information on the Internet and tried a lot of methods, but I still didn't get any help...

Later, I thought about it. Since it was a background modification, it should be related to the database,

Go to the database (my database name is test) and find the table "WP [_ itestoptions" (note that this test may be different from yours ), the value of "option_name" is the value of "option_value" corresponding to siteurl. Change it to The value before modification...

Finally, re-open the page OK...
