[Plugin: WordPress Backup to Dropbox] Wp-admin doesn't work after last update.

After last update, backups are done fine, but suddenly a lot of pages from the core are not running. I only can acces to the dashboard and a few more. I need to eliminate the plugin manually with FTP. I’ve tried to reinstall and the same problem again. It solves when I eliminate the plugin. ??
