PHP Fatal Error: Uncaught Error: Call to undefined function – OJS

bindtextdomain

  • Error 500 while setting distribution
  • The 500 error in registration page
  • PHP Fatal error: Uncaught Error: Call to undefined function bindtextdomain() in /lib/pkp/lib/vendor/sokil/php-isocodes/src/AbstractDatabase.php:87
  • Failed AJAX request or invalid JSON returned

If you get a message like this:

PHP Fatal Error: Uncaught Error: Call to undefined function bindtextdomain() in ...

…then your PHP installation is missing support for the gettext extension. You need to install or enable it.

OJS Email Sending Problem

  • There was a problem sending an email message. Please try again later, or contact your system administrator.

At first, check whether Principal Contact details were added in Journal. Then go for Step One.

Step One

Turn on SMTP in config.php

[email]

; Use SMTP for sending mail instead of mail()
 smtp = On

; SMTP server settings
 smtp_server = mail.example.com
 smtp_port = 25

; Enable SMTP authentication
; Supported smtp_auth: ssl, tls (see PHPMailer SMTPSecure)
 smtp_auth = ssl
 smtp_username = username
 smtp_password = password
;

You contact hosting provider to get the SMTP details

NB: If the above setting does not work anyway, then go for adding envelop sender.

Step Two

Allow envelop sender

; Allow envelope sender to be specified
; (may not be possible with some server configurations)
 allow_envelope_sender = On

; Default envelope sender to use if none is specified elsewhere
 default_envelope_sender = my_address@my_host.com

; Force the default envelope sender (if present)
; This is useful if setting up a site-wide no-reply address
; The reply-to field will be set with the reply-to or from address.
 force_default_envelope_sender = On

Make sure to match the domain in your default_envelope_sender with the domain of OJS installation. If it doesn’t match this increases the spam rating.
