Calendar and Profile image error

Hello there, I just purchased this script, I it nice and simple and it will be handy in my project… I have 2 issues to report:

1- in add user page the calendar is not working and not saving the selected date and showing the following error:

++++++++++++++++++++++++++++++++++

Deprecated: strtotime(): Passing null to parameter #1 ($datetime) of type string is deprecated in C:\serverx\www\login\manage_users.php on line 126 Call Stack #TimeMemoryFunctionLocation 10.0003365344{main}( )...\manage_users.php : 0 20.0066433208 strtotime ( $datetime = NULL )...\manage_users.php : 126 01/01/1970” />

++++++++++++++++++++++++++++++++++

2- the user profile image (avatar) is not showing in the top right corner but the default image still showing, also in the edit user form the image is not showing, while is is uploaded and found in the upload folder…

Regards

Note: I’m testing the script on my local machine wamp php 8.1

To save the cropped image.

Can you please edit manage_users.php file

and replace 

<input type="text" id="dob" name="date_of_birth" class="form-control" 
placeholder="<?php _e("Date of Birth"); ?> 2013-12-03" 
value="<?php 
			$dob = $new_user->date_of_birth; 
			echo date("m/d/Y", strtotime($dob));
		?>" />

with

<input type="text" id="dob" name="date_of_birth" class="form-control" 
placeholder="<?php _e("Date of Birth"); ?> 2013-12-03" 
value="<?php 
		$dob = ( ! empty( $new_user->date_of_birth ) ) ? date("m/d/Y", strtotime($dob)) : ''; 
		echo $dob;
	?>" />

From line 122 to 127

After Fix: this error:

Image issue solved... Thanks

You can edit users.php in lib >> classes >> users.php 

and find out this line at 804

if($password_hash == "argon2") {
	$options 		= ['cost' => 12];
	$password_con 	= password_hash($password, PASSWORD_DEFAULT, $options);
} else {
	$password_con = md5($password);
}

below that line please add

$date_of_birth = ( ! empty( $date_of_birth ) ) ? date( "Y-m-d H:i:s", strtotime( $date_of_birth ) ) : '2000-01-01 00:00:00';

It should fix the problem you are facing thanks.

<input type="text" id="dob" name="date_of_birth" class="form-control" 
placeholder="<?php _e("Date of Birth"); ?> 2013-12-03" 
value="<?php 
		$dob = ( ! empty( $new_user->date_of_birth ) ) ? date( "m/d/Y", strtotime( $new_user->date_of_birth ) ) : '';
