 * Hi,
    New to the plugin — recommended by another great plugin developer, but my
   php error log filled up! Couldn’t do much w/blog (also do anything not related
   to backup) after that as the errors came in every few seconds. Deactivated it.
   Version 2.4.1 on WP 3.8 latest. VPS Server Type: Apache Operating System: Linux
   PHP: 5.3.27
 * The 1st test backup went fast and equivalent to phpMyadmin.
 * Main error log item coming in:
    [21-Jan-2014 00:19:19 America/Chicago] PHP Warning:
   json_encode() [function.json-encode]: Invalid UTF-8 sequence in argument in /
   home/username/public_html/wp-content/plugins/backupwordpress/classes/class-schedule.
   php on line 739
 * Also these many times:
 * [21-Jan-2014 00:03:34 America/Chicago] PHP Warning: shell_exec() has been disabled
   for security reasons in /home/username/public_html/wp-content/plugins/backupwordpress/
   classes/class-requirements.php on line 277
 * [21-Jan-2014 00:04:13 America/Chicago] PHP Warning: shell_exec() has been disabled
   for security reasons in /home/username/public_html/wp-content/plugins/backupwordpress/
   classes/class-requirements.php on line 254

 * We should suppress this with `@`

 * Would be interesting to get a stack trace on this to understand what the argument
   was that is causing the error.
 * Could you `var_dump` the argument that is being passed to `json_encode()` in `
   class-schedule.php`.

   schedule.php.
 * What dump request would work best? Where from?
 * Would I capture it on wp-config debug modes:
    // Enable WP_DEBUG mode define(‘
   WP_DEBUG’, true);
 * // Enable Debug logging to the /wp-content/debug.log file
    define(‘WP_DEBUG_LOG’,
   true);
 * // Disable display of errors and warnings
    define(‘WP_DEBUG_DISPLAY’, false);
   @ini_set(‘display_errors’,0);
 * // Use dev versions of core JS and CSS files (only needed if you are modifying
   these core files)
    define(‘SCRIPT_DEBUG’, true);

 * Sorry, I meant could you edit the class-schedule.php file and place a debug_backtrace()
   in the code before that json_encode line.
 * If you are not familiar with what the above means then I wouldn’t attempt it 
   though as you may end up breaking your site.
 * We’ll have both these issues fixed in the next minor release.
