Did you try having DeadlyBossMods as the only enabled addon and everything else (especially something like ElvUI) disabled?

Which version of DeadlyBossMods are you using?
DBM-PvP-r76-2-gd8c02ac-classic / DBM 1.13.24-classic
Was it working in a previous version? If yes, which was the last good one?
