My website was https://www.example1.com now I have just replaced the siteurl with https://www.example2.com. My website is working fine with new url. but the problem is with wp-admin page. When I am accessing it, it is showing

Sorry, you are not allowed to access this page. 

If I just change the url it works fine again but not with new url.

Could you please tell me what is the mistake I am doing

Thanks in advance!

Note: My website is on godaddy's plask server

There are all sorts of internal links in WordPress sites. When you migrate a site from one URL to another it's best to use a migration plugin. I like Duplicator, but there are others. The migration plugins fix up all the internal links and other stuff.

You may be trying to display a backend page from the old site, because some link or other did not get fixed.

And, don't forget to visit Settings / Permalinks and make sure the permalinks on your new setup are the same as on the old.
