Since wpForo doesn't provide any login/registration functions but only a "form" for it, that error comes from Wordpress core or some other plugin you use.

Hi

Please try and reset the password on this very forum and see the error yourself.

I agree this is originating in Wordpress core, but you should be processing it. In the wp-login.php for example they do this;

$errors->add('invalidcombo', __('<strong>ERROR</strong>: Invalid username or email.'));

Invalidcombo is the error type not the message....

@mistral,

This error doesn't come from wpForo. There is no such error message in wpForo.I searched in whole code of wpForo plugin and didn't find. This is not wpForo code. Please let me know where you found this code. What is the file and directory name?

Some plugin uses WP hooks and adds its error on Password Reset process. wpForo only provides forms and pages but the error message come from other plugins.

I'm not sure you have read my response. In any case I will try and provide some more feedback.

Yes, the error is coming from Wordpress core. For some reason that particular error will not return a nice error string. So in wpforo you have this line, the bold bit actually returns null.

Line 1944 wpf-hooks.php

WPF()->notice->add(join( ',', $errors->get_error_codes()), 'error');

In the standard wp-login.php around line 335 they check if there is no error code and add a new error to fix this.

if ( $errors->get_error_code() )
   return $errors;

if ( !$user_data ) {
   $errors->add('invalidcombo', __('<strong>ERROR</strong>: Invalid username or email.'));
   return $errors;
}

With a small bit of refactoring you can also take measures to see if the get_error_codes() returns null and add this error.

Hope that helps
