G'day, I have just started doing my updates but I am unable to access my setup screen for /sui. I can't type anything in the dialog box either so I can't open it that way. I have just finished downloading 6.0.8-3-g112b498.zip. I have Bartender4-4.10.2.zip and sexymap-v9.0.2.zip.

Everything is updated correctly but both the ui and bartender aren't working.

Can't even really start to figure out your issue just from your quick description. Download/install 2 addons...BugGrabber and BugSack. Then login to the game, there should be a sack icon on your minimap. Click the sack and it should bring up a frame with whatever errors you're getting. There should be an option to export that data so you can post it here. I had a similar issue several months ago when I was trying out ElvUI and some of it's plugins. Couldn't move, couldn't access menus, and chatbox was unusable. Come to find out it was an issue with 1 of the plugins...Project Azilroka...the author had bundled in an addon called iFilger that was having serious conflicts with some of my other addons. Simply deactivated that particular option in the plugin and everything unlocked.

Please do this and let me know the errors.
