I am having a white screen of death appear when a user post a form that I made. Interesting thing is when I as the admin of the site (this site is run using wordpress) post the same data in the form and submit it works, but when a user does it does the white screen, and help. Below is the form data and some other code I am using.
Here is the code that is for the form part (I know it is not great code I am still learning)
function bio_form(){
global $wpdb, $current_user;
//get current user info
get_currentuserinfo();
$yes = $_GET['submitted'];
//check log in
if(!is_user_logged_in()) {
//user isnt logged in
echo "You must be logged in to use this form";
//show login form
if (!(current_user_can('level_0'))){
echo "<h2>Login</h2>";
echo "<form action=" . get_option('home') . "/wp-login.php method='post' enctype='multipart/form-data'>";
echo "<input type='text' name='log' id='log' value='" . wp_specialchars(stripslashes($user_login), 1) . "' size='20' />";
echo "<input type='password' name='pwd' id='pwd' size='20' />";
echo "<input type='submit' name='submit' value='Send' class='button' />";
echo "<p>";
echo "<label for='rememberme'><input name='rememberme' id='rememberme' type='checkbox' checked='checked' value='forever' /> Remember me</label>";
echo "<input type='hidden' name='redirect_to' value=" . $_SERVER['REQUEST_URI'] . " />";
echo "</p>";
echo "</form>";
echo "<a href='" . get_option('home') . "/wp-login.php?action=lostpassword'>Recover password</a>";
//add register link
} else {
echo "<h2>Logout</h2>";
echo "<a href=" . wp_logout_url(urlencode($_SERVER['REQUEST_URI'])) . ">logout</a><br />";
}
}else{
$gg = false;
if($yes == NULL){
$id = $_GET['enID'];
$em = $_GET['em'];
$sub = $_GET['submit'];
if($id == NULL || $em == NULL){

If anyone can help here that would be great. I am wondering if it has to do with the post data, for instance, This is a sample of the url when the form is submitted.

It is really long, and there is many things in it, I am wondering if that is the issue, though as I said when I use the same above string it works fine for me when I am logged in as an admin.
P.S sorry that code didn’t format well in the code block.
White screen usually means crash because of error. I recommend try search error by adding to php code line:
Error not be printed if error occurs bellow this line.
Also do not forget check if no error return from database (mysql, mysqli, PDO.. using different functions to get error).
