Hello,

Since the new update from yesterday it's not possible to login anymore on the website. My logs show the following errors:

Same error. In Simple_Login.php on line 514 you try to concatenate an array when $errors is an empty string.
A temporary solution could be:

$errors = implode( ‘, ‘, $errors );
to
if ( is_array( $errors ) ) { $errors = implode( ‘, ‘, $errors ); }

@anik-fahmid unfortunately due to privacy reasons I can't provide you with the login to my website. I am willing to take the time and provide you with more logs if needed. Please let me know what you would require.

[gossdhosting]

The issue is still not resolved.

@sapayth and @anik-fahmid we're still waiting for a solution. Rolling back to 4.0.12 seems the only solution for now... Could you provide us with an update?
