Actually Download the LATEST version:

• Make sure you are not running disembeded.
• The latest developer build is on WoWAce. Please make sure your bug has not been fixed in the developer build before logging a bug.
• Once you think you have downloaded AutoBar, see Files Required for AutoBar to work below and make sure you actually did download AutoBar
• Completely quit Wow and restart. Did the bug go away?

Narrow it Down:

• Download and install Buggrabber and BugSack.
• Use the BugSack UI (Data Broker icon or /bugsack) to turn off Throttle at excessive amount then log out.
• Disable all other mods except AutoBar, BugGrabber and BugSack. Log in. If you still get the error then it may be an AutoBar bug.
• Otherwise keep adding half of the disabled mods back etc. & narrow down which one is causing an error for you.

What error is causing it:

• Another potential source of bugs are script errors, especially during startup.
• Buggrabber records all bugs and lets you list them using the BugSack UI.
• Ideally there should be no errors. BugSack gives you a very nice UI for the !Buggrabber errors as well as options for bug tracking, and the ability to copy and paste errors.
• Startup errors in a particular mod probably mean it is not going to work correctly.
• Please only report the first bug. The first one usually leads to a cascade of meaningless bugs that may or may not even be real.
• Please state what version you are running when reporting a bug, it saves a lot of time and confusion.
• If you download off of wowace you need to report the SVN revision number (r#####) as well as the official AutoBar version number. You can find both in the title of the AutoBar options window.

Reset the Saved Variable File:

• AutoBar is constantly changing. Mistakes can happen. Perhaps the Saved Variable File is corrupted.
• You can save this file first if you dont want to lose your settings. If it does not fix your issue then just quit Wow, restore the file & relog.
• Quit completely from WoW, then delete:
• World of Warcraft\WTF\Account\<YOUR ACCOUNT NAME>\SavedVariables\AutoBar.lua and AutoBar.bak.
• Restart WoW.

NOTE: Resetting the saved variables file should almost never be necessary. Even as the developer I have done this less than 5 times in the many years I have worked on this. So be sure to save the file and restore it if it has nothing to do with your issue.
