So yesterday I decided to update the forum after I read that there is a new version available.
Me sometimes roaming around looking for news *cough* hours per day *cough* I already heard that there was a much better version coming with much easier mod (now called extensions) integration.
I instantly made a backup of the forum and database and redirected everyone to a temporary page indicating that the forum was under maintenance.
I pulled it off, all mods are gone because they are all incompatible but it was worth it.
I did install an extension and it works so much nicer than the previous method of installing mods.
