Problem after restore

Hello,

Because of an unsuccessful update of the Jetpack Pluging I had no access to my site. The public site was down and the WP backend was not accessible.

I have restored the backup done previously with your plugin by copying the file structure of the backup file to the server via ftp connection using Filezilla.

The public website is now online again and seems to function. I also get a login screen. But after loggging in, I only get a blank webpage and no access to the WP interface.

What do you suggest to do?

Thanks for your help!

Kind regards

Frank
