When accessing WordPress installation under Home > Subscriptions > > Applications > Manage My Applications the following error appears:

Decoding failed: Syntax error 


  • To find the cause of the issue execute the following command:

    # /usr/local/psa/admin/bin/wpmng --user=subscription-user -- --path=/var/www/vhosts/ core info --format=json


  • Check Apache /var/www/vhosts/system/ log for the issued domain.


For example:

  • the command mentioned above was executed:

    [root@server ~]# /usr/local/psa/admin/bin/wpmng --user=subscription-user -- --path=/var/www/vhosts/ core info --format=json
        <!DOCTYPE html>
        <html lang="de-DE" id="wp_maintenance_mode">
                <title>Reethdach Ferienhaus</title>
                <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
                <meta name="author" content="WP Maintenance Mode: Frank Bueltge," />
                <meta name="description" content="Reethdach Ferienanwesen - Neu renovierte Reethdachhäuser mit Sprossenfenstern, viel Charme und Licht!" />
                <meta name="keywords" content="Maintenance Mode" />
                <meta name="robots" content="index, follow" />
                <link rel="Shortcut Icon" type="image/x-icon" href="" />
                <link rel="stylesheet" type="text/css" href="" media="all" />
               <link rel="stylesheet" href="" type="text/css" media="all" />

    As can be seen, there is stub page on main website page from 'WP Maintenance Mode' WordPress plugin (if such plugin is enabled in the WordPress instance, WordPress Toolkit will not recognize it). To resolve the issue disable the plugin:

    # mv /var/www/vhosts/{,.bak}
  • The following error can be found in /var/www/vhosts/system/ file:

    [root@server ~]# tail -f /var/www/vhosts/system/
    PHP Parse error:  syntax error, unexpected '*' in /var/www/vhosts/ on line 93

    As can be seen from the error, /var/www/vhosts/ file should have correct syntax.
