I'm trying to update so I can use the ConfirmAccount extension. It failed to work using the Mac Terminal app, so I want to do it through the browser.
The problem is that it tells me that the upgradekey that I copied from local settings isn't accurate. I know it is copied correctly, and I have not changed any values.
Please help? I've spent almost four hours on this issue, and I'm ready to tear out my hair. I'm using version 1.29 of MediaWiki.
