I have always used Xenforo v1.x.x in the past, I only recently tried out v2.x.x, in the addon, one of my addons seem to have a sql error, something about array error, anyhow, it keeps saying pending and not sure how to remove that. Should I just delete the files that I uploaded very carefully and hope it removes it, or is there a more easier way to do this? Thanks.. Sorry if I sound to lame for this, but we all gota start somewhere.
