Why did dbtech website loose so much traffic during 1 month, because of xenforo?


I noticed the dbtech website went from 600k to 42k visitors, the biggest drop was almost during 1 month back in sept,oct

im guessing this is because the change from vbulletin to xenforo? i remember this site was on vbulletin not to long ago,

i dont want to blame xenforo but it's only a guess,


i havent been here that long, but im also surprised at the amount of customers still asking for vbulletin support here,
i thought vbulletin was dead
