    Hey @shiponkarmakar – thanks for the report. Just to clarify – you were having trouble actually running the update to RC3 with the Beta Tester plugin installed.

    Can I ask if you try again now, if the problem persists?

    Your post has been marked resolved.

    Once the alpha version of WordPress is released, or more than a month has gone by without response, we “resolve” posts as a bit of a sanity check. It lets mods and volunteers know we don’t have to jump in and find an issue.

    If you’re still having this issue with the newly released/current version of WordPress, please make a new post in
