Q&A Plugin error message when editing new user question

Hi. I am still waiting for a reply a couple of days later re this…
https://premium.wpmudev.org/forums/topic/error-when-editing-user-qa-visitor-question-while-logged-in-as-admin#post-663752

Are your staff helpers paid or is the support voluntary? Also, my membership for the Q&A plugin runs out in 2 days time.
Does this mean I can no longer contact the help centre?
Also, please advise the latest version of the Q&A plugin – I should have the latest (v 1.4.3.5) but the forums talk about features in the latest version that I don’t have, e.g. being able to set a default category in the settings.

Kind regards,
