Recent Update Prevents Login to WP

Hi:

After updating to the most recent version of UpDraft, I was locked out of my website. I was unable to login to wp-admin.

I contacted my hosting company, who were able to deactivate Updraft after discovering that it was interfering with the login process. This is what they shared with me:

Your error is the result of your team updating the updraft plugin. You
> updated it yesterday at 5:32PM ET. That is one of 5 plugins that your team

I’m not fluent enough with html to understand what all of that means but I expect you are. Would you please shed some light on the cause of the conflict, correct it and advise us when it’s safe to re-activate it.

Thanks for your time,
Miguel
