Post installation errors

Hi, beginner here.
I installed suitecrm 8.4 on xampp-windows-x64-8.2.4.
My system specs: * Apache/2.4.56 (Win64) OpenSSL/1.1.1t PHP/8.2.4

I installed suitecrm and sample data… No error during setup, but I have no admin page and if I click on an user (sample data user) this message shows:
Deprecated : Return type of Symfony\Component\HttpFoundation\Session\Attribute\AttributeBag::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in C:\xampp\htdocs\suitecrm\vendor\symfony\http-foundation\Session\Attribute\AttributeBag.php on line 134

No one ?
Does anyone have a suggestion for me?
I am stucked.
Thank you.

Those errors are not relevant. You simply have to turn off the option that dumps them on the screen (they should just go into the logs).

Check instructions for your XAMPP version regarding display_errors setting.

Thank you @pgr .
I disabled the option to dump this kind of error in php.ini.
But now if I click on an account (sample data) or a contact (sample data) suitecrm take me back to login page :frowning:
Any other advice ? Thank you again.

Now you have to check the logs! :slight_smile:
