With SimpleRisk 20170102-001, we converted several of the pages to use javascript AJAX queries against the API functionality.  To get SimpleRisk to work properly, you will need to do the following:

For Apache:

1) Enable mod_rewrite by running the comand "a2enmod rewrite".

2) Open the file containing the Apache site configuration.  This is likely found under /etc/apache2/sites-enabled.

3) Find the "Directory" section for your simplerisk site and add a line at the top for "AllowOverride all".  It should look something like this:

<Directory "/var/www/simplerisk">      
        AllowOverride all                          
        allow from all                                
        Options -Indexes                          

4) Restart Apache by running the command "service apache2 restart".

For Nginx:

1) Make sure the HttpRewriteModule is installed.

2) Specify the following inside of the SimpleRisk server configuration:

location ~ /api {
  if (!-e $request_filename) {
    rewrite ^/api/(.*) /api/index.php?__route__=$1 last;

For IIS:

1) Make sure the URL Rewrite Module is installed.

2) Specify the following inside of the web.config file inside the SimpleRisk web root:

<?xml version="1.0" encoding="UTF-8"?>
                <rule name="epiphany" patternSyntax="Wildcard">
                    <match url="api/*" />
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                    <action type="Rewrite" url="api\index.php?__route__=/{R:1}" appendQueryString="true" logRewrittenUrl="true" />
