Yes I have to do that, which means all the customization and mods I've added to this site will be gone and I have to start over.
Thanks for the reply. On the Admin Center page there is a notification asking you to update the SMF version to 1.1.20, why don't you try that first before installing 2.1? It says "it only takes a minute", maybe it will fix the bug so you don't have to install all of the mods again. I think you can apply the update via the package manager...
