Password Protected Visibility Redirection Issue

I was trying to make a page only visible to users with passwords.

So thought about trying it out for testing and made a simple demo page and set visibility to password protect and then published it.

Now, when I am giving the password, instead of opening the page content it is redirecting to the following /wp-login.php?action=postpass.

I am not using any plugin, it’s just the normal method applied by changing visibility in WordPress post or page. WordPress is also updated to the recent version.

Just got an advice from a close friend to deactivate all plugins and find where the issue is coming from. And it turned out to be ithemes.

So, please help me fix this issue.

Thanks in advance!
