Hi,
I have already done this but still there was no different result

What’s in the debug log?

I have installed a debug plugin recently and it is showing “Deprecated: registration.php is deprecated since version 3.1.0 with no alternative available. This file no longer needs to be included. in /home/sanchita/public_html/wp-includes/functions.php on line 5411”

What is in the debug log?
