XF 2.0 InvalidArgumentException: Accessed unknown getter - XF:Forum[118] src/XF/Mvc/Entity/Entity.php:182

[Big Boss]

Field: find_new
Gives error when I saved any forum. But error is hidden, only saving to log file.



XenForo: 2.0.12

Thanks in advance

This is a PHP 7.3.0 issue. You should upgrade to 7.3.1.

Thanks. I use PHP 7.2.12 version, I'll upgrade to 7.3.1

Thanks. I use PHP 7.2.12 version, I'll upgrade to 7.3.1

Before upgrading to php 7.3.1 try to disable the add-ons and see if the error still exist because I run the same version of yours xF2.0.12 with PHP 7.1.25 and I haven’t seen this error before.

In fact if you’re not running PHP 7.3 yet then we may have been mistaken over the cause and I wouldn’t necessarily recommend upgrading yet.

In fact, it might be easier to submit a ticket with Admin CP log in details and FTP access, so we can take a more detailed look.
