Thank you for the quick response!
Yes it’s very strange. I tried your link, but it tells me:

App not active
This app is not accessible right now and the app developer is aware of the issue. You will be able to log in when the app is reactivated.

I will try to troubleshoot this and I will keep you up to date.

Thank you again!

Ok so it still happens with PHP 8.0

Very strange. It looks like usernames and email addresses are returned blank. First name and Surname are correct.

Any ideas?

OK it appears that this issue is the one preventing logins. This is true if the user is new.

Line 1776 of class.wp.w3all-phpbb.php has this function:

public static function wp_w3all_get_phpbb_user_info($username){ // email/user_object/username

 global $w3all_config,$w3all_phpbb_connection;

 $username = trim($username);

       if ( empty($username) OR strlen($username) > 50 ){
         echo '<p style="padding:30px;background-color:#fff;color:#000;font-size:1.3em">Your <strong>registered username on our forum contain characters that are not allowed on this CMS system, or your username is too long (max 49 chars allowed)</strong>: you can\'t be added or login in this site (and you\'ll see this message) until logged in on forums as <b>'.$username.'</b>. Please return back and contact the administrator reporting about this issue. Thank you <input type="button" value="Go Back" onclick="history.back(-1)" /></p>';
           die("<BR>Username[".$username."]<BR>"); // <<--- I ADDED THIS LINE
           return false;
       }

  if (isset($username->user_login)) {
    $username = trim($username->user_login);
  }

 if(is_email($username)){
  $username = strtolower($username);
 } else { $username = mb_strtolower($username,'UTF-8'); }

  $username = esc_sql($username);
  $db_eu = is_email($username) ? 'users.user_email) = \''.$username.'\'' : 'users.username) = \''.$username.'\'';

    $phpbb_user = $w3all_phpbb_connection->get_results("SELECT *
    FROM ". $w3all_config["table_prefix"] ."groups
    JOIN ". $w3all_config["table_prefix"] ."users ON LOWER(". $w3all_config["table_prefix"] . $db_eu ."
    AND ". $w3all_config["table_prefix"] ."users.group_id = ". $w3all_config["table_prefix"] ."groups.group_id");

 return $phpbb_user;

}

As you can see I added the line:
die("<BR>Username[".$username."]<BR>");
so I could troubleshoot the issue.

$username is an empty string. That is the cause of the error I was seeing in this post, and in my previous post (https://www.ads-software.com/support/topic/facebook-login-47/)

Is this some PHP restriction? I am running PHP 7.4 FastCGI

Also, which option should I have set?

Hello!

I just tried the link for your test site and it looks like your Facebook App is no longer active:

“App not active: This app is not accessible right now and the app developer is aware of the issue. You will be able to log in when the app is reactivated.”

My website is not a multi-site. WordPress and phpBB3 are on the same server. My Facebook name is a normal name, only letters and a space, no numbers, no symbols.

I’ll will go back and try again. Thank you so much for your support!!
I’ll let you know how it goes.

Hello!

Please disregard. I figured it out. I was using the wrong table prefix in the phpBB3 extension. I couldn’t find how to delete this post.
Great news about the ACP functionality!
Apologies for wasting your time and thank you so much for such an invaluable plugin!

Will be donating via PayPal. I hope you get lots of other donations. A lot of work went into these plugins/extensions.

Thanks!!
