    do you have a recent backup of database and files
    looks like a problem with revolution slider
    can you temporarily rename the revolution slider plugin’s folder via File Manager or FTP? (this will deactivate the plugin so you can start further troubleshooting)

    Looks to me like you have a problem with the Slider Revolution plugin. Are you using the latest version?

    To get your site back, delete wp-content/plugins/revslider, then reinstall the latest version.

    If that doesn’t fix it, contact the deves. You’re using a commercial plugin, so please use their official support channel. We feel they are best equipped to support their products.

    Commercial products are not supported in these forums.

    I don’t have any backups, only access to ftp, and I try to transfer a page to a new hosting.
    I tried to rename revslider folder earlier, but other errors appear:

    Warning: Illegal string offset ‘remember’ in /wp-includes/user.php on line 41

    Warning: Cannot assign an empty string to a string offset in /wp-includes/user.php on line 41
