Sorry, I meant to update this post a few days ago. The problem is solved, and was linked to this error. Essentially, a must-use plugin from 1&1 caused Contact Form 7 to fail silently, so that no data was actually read from the form, which seems to have caused the issue with Conditional Fields.

1&1 has since then disabled the plugin (I believe it was something along the lines of “cosy-addressbook”) and everything is working again now. As such, there’s not much you can do about it (save, perhaps, catch the error if Contact Form 7 returns data like [your-name]?).

Thanks for responding!
