Most interesting! You make it sound as if someone has hijacked the main PunBB site.
In June last year I was searching for a small simple forum package and opted to try FluxBB. My hosting company provides the service available from Softaculous so until now I have never self-installed any PHP package, and have been particularly intimidated by those requiring a database.
Back then FluxBB had a more recent update than PunBB, but I never committed to it as I was unhappy with its display on mobile devices, even with the of the supposedly responsive themes. Last week I noticed that PunBB had been upgraded on Softaculous (probably just after I had been looking). It was then that I discovered that PunBB has a very respectable interface on mobile devices.
My forum will only be for a maximum of 12 users and very low traffic. It will just be a shared archive of various papers connected with a set of holiday cottages. You could say it might be better to use Dropbox or GoogleDrive - but I want to allow for some possible discussion that could be generated in the future.
I have now managed to use cPanel's MySQL Database Wizard for the first time and successfully installed your implementation of PunBB. I'll see how that goes!
The List bug is gone!
Thanks for all your help!
