 * We’re using WP 4.8.1 and v2.2.2 of this plugin. We’re seeing the following error(
   and a blank page) were we want to display our uptime monitors:
 * `Fatal error: Call to undefined function bcdiv() in /public_html/wp-content/plugins/
   uptime-robot-monitor/functions.php on line 210`
 * All other plugins have been disabled but the error persists.

 * Hi,
 * Looking at the error it seems like your php compilation doesn’t have the bcmath(
   for calculations) module enabled.
 * To solve this you should enable the module and recompile php or contact your 
   hosting company.
 * For more information: [http://php.net/manual/en/book.bc.php](http://php.net/manual/en/book.bc.php)
 * Regards,
    Niels
