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 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:
<?php phpinfo(); ?>
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.
