OK. I just found the problem.
I have checked the log. and figure out formatting.php has been modified. and I copy from the original file. and problems fixed..

Thanks..

OK. here is all actions I have done. see if it can brings any ideas.

btw: I am not rash at all. just want to figure out this type of issues.
Because I am pretty sure it do happen a lot.

I try to make domain works without www this morning.

I go to General > wordpress site url (I change the wp url to the domain without www). suddenly, all the links stop working which includes admin login page.

Then, I go to mysql database, change the url back to www. meanwhile add htaccess make all the urls point to www.

Everything was working!! I can logon to the admin page. and I did one plugin update. (I am pretty sure admin page works after I update)

I didn’t clear my cache since last year. so I decide to clear the cache.

After clear the cache. admin page won’t left me in. I think that’s all.

Thanks in advances…..

Hi seacoast web design. Thanks for your responses.

Actually, admin page started not working after I clear my browsers’ cache

However, I didn’t try clear plugins’cache I am not sure How to clear it. I have re-name the plugins folder. does it do the same job?

can anyone help?

Resolved. Thanks guys

Thanks for your post. my issues has been fixed.
I have tried to doing something in wp-config before. but it didn’t work.
However, I go through php database, and change the siteurl, and go back to my admin page. change the wordpress url back to http:www.abc.com
finally, add the following codes to .htaccess

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} !^www.abc.com$ [NC]
RewriteRule ^(.*)$ https://www.abc.com/$1 [L,R=301]

now everything is working.

Hi esmi, Thanks for your responses. I have tried, url definitely changed. I can get the admin logon page, but it shows blank when I type in my credential, and enter logon.
