Fatal Error after update to 3.1.6

Hi Henk Jan,

It seems as if the update download only completed partially for you. Can you confirm that the /includes/admin/class-update-optin.php exists in the download package please?

Thanks in advance!

Hi Danny,

Yes, /includes/admin/class-update-optin.php does exist in the download package. Plus, the fatal error occurred only once. And only on my production website – not on my test environment.

Hi Henk Jan,

It could be that your website is running some kind of file or opcode cache which caused the plugin to be in a partial state, in turn causing the fatal error.

Over 30.000 people have installed 3.1.6 by now, so I think it is safe to say that the error is specific to your environment. When you say the error only occurred once, do you mean that it resolved itself now?

If not, let me know please!

Hi Danny, can you help me? I have the following message when I try to login to my domain.com.br / wp-admin:

PHP Fatal error: Call to undefined function apply_filters () in E: \ Domains \ qualymarketing.com \ wwwroot \ TEST \ wp-includes \ load.php on line 316

Can you tell me what the problem is? I believe you know, because the problem of the person above is very similar … Thank you.
