changed url and now i cant find my site

Change the urls back. See Changing_The_Site_URL for details of how to do this correctly.

thanks but i cant login to the site anymore

Now try reading the page at the link I posted above. None of the suggestions made require you to login to your WordPress dashboard.

thanks a million.

last thing please, how do i change my domain now from khethani.co.za/wp to https://www.khethani.co.za?

See Giving WordPress Its Own Directory

sorry guys i’m still struggling. I tried to copy the index.php but think i must have messed it up. Now whenver i click on a page: https://khethani.co.za/wp/ it wont load.
Would appreciate any assistance
Thx!

Who said anything about copying files? See Giving WordPress Its Own Directory.

that link says: Copy (NOT MOVE!) the index.php and .htaccess files from the WordPress (wordpress in our example) directory into the root directory of your site

There no files in your root domain folder.

you need to log into the mysql database of the wordpress database and change the path in there as it will have entries relating to your old path. or simple change the path to the old path on ftp. then go into wordpres wp-admin change it both in there, then start moving files about in https://FTP..

thanks funkywebsites. Please can you help with another thing? When making the changes I seem to have done something to my site https://www.onlineteetimes.co.za. Can you help to sort it out?
thanks

it looks like you have deleted the index.php
