Error: Invalid argument supplied for foreach() on line 183

Same here … Error message in the first 2 lines of the exported spreadsheet.
Any solution for this?

if ( $usermeta && is_array($usermeta) ) {
  foreach( $usermeta as $field ) {
    $usermeta_fields[] = $field;
  }
}

Line 183 expects $usermeta to include an array of values – I presume you selected no usermeta fields – this is a bug in the plugin, but this fix should sort it – FYI – I’ve not tested this yet.. but will and if it’s good, I’ll release an update.

Q

I could not replicate this error, however I’ve released an update to the plugin which should address the problem.

I would also strongly advice that you set-up your wp_debugging to log to a file – as described here: https://codex.www.ads-software.com/Editing_wp-config.php#Configure_Error_Logging
