====== Troubleshooting ======

Following is a list of troubles our users had with previous versions of Instant Update. Please note that most of these troubles are server side issues which can be solved in 90% cases by using **.htaccess** (server configuration) file if PHP is installed as server module, or using **php.ini** file if PHP is installed as CGI module. 

To see if your PHP is installed as CGI or as server module, you can use our [[http://www.instant-update.com/plus/selfcheck-script.zip|selfcheck script]] which can tell you very much about your web server, including this, or you can create blank text file, name it **phpinfo.php** and place it in the root of your web site. After that, fill it with following code:

<code php>
<?php
phpinfo();
?>
</code>

After that, navigate your browser to //yourwebsite.com/phpinfo.php// and take a look at "Server API" item in table. If it says "CGI" then your PHP is installed as CGI module and you need to use **php.ini** file in the root of your website to solve most of these problems. Otherwise, you'll need to use **.htaccess** file.
