 * Hi,
 * Please check if you have php7.0-xml installed.
 * This may be causing the issue.
 * In case you are the webmaster, please try to install php7.0-xml using the following
   command on your hosting server: “sudo apt-get install php7.0-xml”
 * This tutorial can help [http://stackoverflow.com/questions/31206186/call-to-undefined-function-simplexml-load-string-in-cron-file](http://stackoverflow.com/questions/31206186/call-to-undefined-function-simplexml-load-string-in-cron-file).
 * What might have happened is when php was upgraded, not all the modules from the
   previous version were compatible with php7.0, thus the simplexml_load_string()
   was not loaded because the module containing it was incompatible.
 * But please be advised of the fact that the previous steps have not been tested
   by us, so we cannot guarantee that this will fix the problem. It is not a plugin
   issue, but a hosting issue so please take full responsibility for the changes
   that you will make on the server.
 * If you are not the webmaster, please forward this response to him.
 * Hope this helps.
