redirection after register, or forgotten password, or incorrect password

Hello,
I work with joomla 5.4.1 and CB 2.11.
When a user try to register, CB tries to go load /component/comprofiler/saveregisters which doesn't exist, so the home page of my website is displayed.
On the CB Login module, I can set the redirection for a user who succeed in logging in, but in the other case, I don't understand how to set the redirection, and how to display some messages like “Your password is incorrect. Please try again.”
“Your email address has been validated. You will soon receive an email to log in.”
“A validation email has been sent to you. Please check your inbox.”

Can somebody help me ? Thank you wery much

That page does exist so no you should not be being redirected to your home page. It has no menu item associated with it because you're not meeting the requirement of having a published and public Joomla menu item to CBs profile page, which is used as a fallback menu item for any internal endpoint. Once you've fixed that it should display fine.

This should've already been created for you on first install of CB under the Community Builder menu type and should be named "CB Profile", which you can of course rename, but it still must exist as public and published. Profile access itself is configured in CB > Configuration > User Profile.

Thank you Krileon for your answer.

I wanted the access to the CB profile item menu to be possible only for registered, authors and admins but not for guests, under a "My Account" menu parent => that was the origin of my problem.
So, I moved the CB profile item menu to a hidden menu, set it for Public access, and created an alias below "My Account", keeping it visible for  registered, authors and admins.
Now it perfectly works, thanks to you !!

See you
ND.
