Yes I've copied all the files from my previous installation, i've not done any new installation.
The error is:
Fatal error: Call to a member function bind() on null in phar://************************/include/plugins/auth-ldap.phar/authentication.php on line 220
In line 220 There is a call to the bind method:
$r = $c->bind($dn, $password);
$c should be $c = $this->getConnection(); but this returns NULL.
PHP 5.6
please, can you help me?
