Errors

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.

I have updated the issue.
How can it be reopen?

But before you reopen it, please manually delete my ElvUI_MerathilisUI folder from your AddOn folder and download a fresh copy

Without giving me any useful infos (ElvUI Version? MerathilisUI Version?), and a way to reproduce the error, i will immediately close this. Also, Discord should be the first way to join if you have issues or trouble.

Feel free to reopen this if you updated this ticket.
