Fatal error: Call to undefined function

Resolved

(@alexwbaumann)

After upgrading from 3.7.8 to 3.15.0 using php 7.2.11 (mstring and iconv seem to be enabled) when accessing the pages in the admin, I am getting the following error.

PHP Fatal error:  Uncaught Error: Call to undefined function Symfony\Polyfill\Mbstring\iconv() in /home/[username]/public_html/wp-content/plugins/mailpoet/vendor/symfony/polyfill-mbstring/Mbstring.php:114

Hi there @alexwbaumann,

Can you double check via your PHP info that iconv and mbstring are installed and enabled? If you aren’t sure how to do that, you can do it via using the Health Check plugin; https://wordpress.org/plugins/health-check/

If they are enabled, please contact us via https://www.mailpoet.com/support/wordpress-forums/ so we can debug further.

Thanks!

phpinfo shows –enable-mbstring=shared and –with-iconv=shared. Will head over to the link provided to open a ticket there.

Whoops. Turns out, while enabled in php configuration, the configs were not being loaded. Got that fixed and everything is working.
