To resolve them, I just performed a long due upgrade of the forum software.
As a result of the upgrade, your experience on the forums will change slightly.
I tried to reproduce a very similar layout to make it easy for everyone - I hope you'll enjoy it. Feel free to report anything you dislike and we'll see if that can be improved.
Unfortunately, as you may have noticed, the transition didn't go smoothly : the website was offline for most of the day today... and I've been forced to restore a backup of the database dating to this Monday 2020-10-12 06:28:37 GMT. Any post or conversation, and any work done on a trial since that date has disappeared.
I'm really sorry for that problem - but given the trouble I've gone through today, I'm already relieved to get everything back online now !
