Answer 1

Check the init.php and dbcon.php files in the /bitrix/phpinterface folder.
Remove the closing tag ?> from these scripts.
That is, there should be no closing PHP tag ?> at the end of the file!
Check the init.php file to see if any HTML tags are output.
Example:

function showPopup(){?>
<div class="popup"></div>
<?}?>

Try to temporarily move all such scripts to header.php or comment them out in init.
Check if the authorization worked.

Answer 2

It is necessary to look at the paths for sessions. By default, something like this
php_admin_value session.save_path /tmp/php_sessions/ext_www/automanarch
php_admin_value upload_tmp_dir /tmp/php_upload/ext_www/automanarch
If these folders do not exist or there is no access to them, then such a problem will be observed.
