I confirm the update is working.
Thank you for the fast response Elliot.
Yes, I get the “PHP Fatal error: Can’t use function return value in write context in /public_html/wp-content/plugins/advanced-custom-fields-pro/includes/local-fields.php on line 304”. Sorry forgot to mention this. If this is indeed a PHP 5.4 related issue, this means godaddy did not update to 5.6, and still runs on 5.4 (even if I did the update). Will check a phpinfo.
This is not a php version issue. Or at least, not on 5.6. I updated PHP from 5.4 to 5.6 (max on godaddy linux hosting) on a customers website and the issue is still there. Maybe on some higher php versions?
Also happened to me just now. I had to get the website under maintenance mode. All content is gone.
L.E.: I confirm, reverting back to 5.7.10 is working. Will wait for updates on this matter before the update.
