So, I update from 2.0.17 to 2.018 and reinstalled mods.
When I used my bookmark to access the forum,
https://gsx1400owners.org/forum/index.php?action=unread
it didn't work.
I had to go to https://gsx1400owners.org/ which defaults to https://gsx1400owners.org/wp and from there click on forum on the menu
