Custom fields stopped working

How exactly they stopped working?

they are written as %CF-whatever% instead of showing their content

You are right. Will be fixed in the next release.

Could you please tell me what to change if the release is not inminent?

Thank you

Fixed in the 3.4.9

Awesome.

I take this opportunity to thank you for your great plugin. It has great documentation, excellent FAQ and it is easy to configure even if there are a lot of steps to follow.

Best regards!
