FAQ
Q: I cannot move/drag my skills on my bars?
A: Hold Shift to move skills safely. You can also unlock your bars in the Bartender4 options, but using Shift is safer and recommended.
Q: How do i access the Configuration?
A: You can open the configuration with the Slash Commands (/bt or /bartender) or through the Bartender4 LDB plugin.
Q: Where are my keybindings? And how do i bind new keys?
A: Bartender4 buttons should automatically inherit keybindings from the Blizzard bars. For new keybindings, you can use KeyBound to re-bind your keys. You can access KeyBound by its slash command (/kb) or through the button in the BT4 config. Hover a button, press key → voila!
Q: Can I skin the buttons beyond the built-in options?
A: Bartender4 allows skinning through Masque! After installing both Bartender4 and Masque, you can customize the BT4 appearance in the Masque options.
Q: How do i disable the snapping of the bars?
A: Currently, you can temporarily override the snapping by holding down the Shift Key while moving your bars, or uncheck the option in the popup when your bars are unlocked.

Posted Mar 24, 2026In reply to sicariusgaming87: Blizzard pushed an unexpected change to the ActionButton.lua code that broke most, if not all, action bar addons. ElvUI as well.
What's worse is that even with no addons, some players are also reporting Lua errors with the same button breakage symptoms reported.
According to AcidWeb on the TukUI/ElvUI discord, Blizzard skipped testing this change on the PTR in order to quickly address concerns with aura/cooldown tracking addons in the RWF.

Posted Mar 24, 2026Unfortunately, I think Bartender has been completely abandoned. This was my number one addon for so many years. I wish someone else would pick it back up and show it some love. I'd pay money for that to happen.

Posted Mar 24, 2026In reply to Villious: In reply to user_yw9boahg0meirsi1: LoL. You must have missed the 6 updates since Midnight was released. It was working fine until Blizzard changed things last minute and has only been live for an hour. As an addon author I hate idiots like you posting that an addon has been abandoned when you have no clue what is actually going on. And it looks like the author just released an update

Posted Mar 23, 2026I have tried updating this addon for weeks now, everytime I do, it just vanished from the game and doesnt even show in my Addon list. This is fior MoP CLassic. I have to revert to a release from December to get it back in game.
