Hi @zebulon, thanks for reporting. A fix will be included in the next release.

The fix can be found here: https://github.com/b2evolution/b2evolution/commit/485a687bea420fd7660bd5a433cb24dc5a82fcf9. In case it's urgent to you to get this working, you can patch your code manually, however, as we always say, this is not recommended.

Regards!
