Login error and taking me redirect page

Did you try accessing /wp-login.php ?

yap, I already tried. but still redirecting me to another page!!!!!!

Can you post your site URL?

https://www.khaledsharif.co.uk/

I was able to access https://www.khaledsharif.co.uk/wp-login.php
Well, i first had to enter the captcha on the “ARE YOU HUMAN” page and then it re-directed me to the login page.
Did you empty your browser’s cache or tried to access from another browser (or computer)?

Yes, I been trying but can not access. it still redirecting me another page instead of entering captcha or login page..

You should definitely rename your plugins folder to plugins.hold to disable them (by FTP) and then try to access your site login page again.

you want me to deactivate via FTP. and change the file name as well.

Follow these steps: Deactivate plugins
Before step 4 check if you can log in

I already tried, but unfortunately can not!!!! concerned!

Why not?
