This will help resolve an issue that presents the symptom of being unable to view newly created risks and/or plan mitigation for them. This is relatively easy to resolve and should be straightforward. An example of the error given when this is the issue is "[Mon Apr 10 12:04:42.761563 2017] [:error] [pid 14498] [client] PHP Fatal error: Call to undefined function mb_substr() in /var/www/html/simplerisk/includes/assets.php on line 464, referer: http:/ /"


Open terminal and type the following command.

"sudo yum install php-mbstring"

Next restart apache using

"sudo systemctl restart httpd"

This should resolve any issues created by a lack of the PHP MBString extension. This fix was confirmed working using Ubuntu 14.04 LTS. This may not work for all operating systems.
