ElvUI Changelog/Troubleshooting

• I have confirmed that I have read the Changelog and done the Troubleshooting Steps.
• I have disabled all addons except the AddOns called 'ElvUI' and 'ElvUI OptionsUI' and 'ElvUI_MerathilisUI' by using /muidebug on? This is important in order to rule out that any of your other addons are causing the issue. If you manage to pinpoint a conflict between ElvUI and/or MerathilisUI and another addon, make sure you include that information.
• I have verfied my issue doesn't exist in the default UI.
• I gave you information above on which XPack i play Classic, WotLK or Retail.
