If by mistake anybody sets the wordpress url option given by the plugin from root directory to some other path for example in my case
I by mistake changed wordpress url from
https://www.skadatraining.com
to
https://www.skadatraining.com/wp-admin
this address this website will crash as pages are no longer available. To solve this
go to Filemanager then public_html folder then view .htaccess file and note down the mysql database name.
After this by Cpanel go to the PHPmy admin
then open the noted one database
under that database open wp_option
Now change the wordpress url mentioned their to one that was previously in use which was in my case https://www.skadatraining.com
Hope this will work out if anybody ever encounters the same problem.
