Hi Kashfi,
I've applied a workaround proposed by A Lahif. However, it's now
accepted by the Arc team and will be part of new release. I suppose that
it's relevant for you that two of my Arc-CEs ahve been in production for
a year (as 4.x) and
were upgraded without any trouble two weeks ago. I only had to do that
minor fix. And the upgrade seems to have fixed an old problem in
publishing to Apel.
The tikcet I opened is here
https://ggus.eu/index.php?mode=ticket_info&ticket_id=113745
Andrew's fix is described in update#44.
Thanks, raul
