hi
@impurnendu
You might also need to add this line in your .htaccess file :
SetEnvIf Authorization .+ HTTP_AUTHORIZATION=$0
If the above line does not work please change the above line to :
SetEnvIf Authorization .+ HTTP_AUTHORIZATION=$1
you need to explain your problem on your topic and for this
we need to check this out on your site so for that you need to provide some details like the course on which we can perform testing
please make sure you have all plugins and theme activated to the latest version
if you need further assistance then I request you to please create your own topic because to check your issue if we want your's admin credentials or page URL of your site then an Email sends to the person who creates this topic with your credentials either you send them as a private reply which is not good.
so for security purposes always create your own topic.
