Hello,
We are facing this issue on our site.
<span style="color: #000000; font-family: Calibri;">When user (any user, old or new) logins from frontend, they dont get logged in, instead they are redirected to "Hello World" page, I tried to set redirection towards Dashboard, but it is not working this way. </span>
It seems you've not set the 404 page on your site, so the login fail is redirecting to a 404 page which is the hello world post.
I would need your site url and sample student credentials to test this and tell you what's wrong here.
It was fixed, there was issue due to 3rd party plugin we used, after disabling it, Login issue got fixed.
OK thanks for confirming, the issue is fixed.
So closing the topic.
