<h1><?php echo APP_NAME;?> Checkup</h1>
|
|
|
|
<p>This checkup allows you to check that your environment is ready to
|
|
support a <?php echo APP_NAME;?> installation, and that you can proceed to
|
|
configure your system. Red items are things to fix. Orange items means
|
|
you may not be having the ultimate experience unless the support is
|
|
added. Green items means you're ready to go in this area. You can
|
|
check back here to see if anything has changed in your environment if
|
|
you have any problems.</p>
|
|
|
|
<h2>.htaccess file</h2>
|
|
|
|
<p>You can let <?php echo APP_NAME;?> manage the PHP settings that apply to the
|
|
<?php echo APP_NAME;?> application (it won't affect your other applications) by
|
|
configuring your web server to use the .htaccess files that come with
|
|
<?php echo APP_NAME;?>. This will ensure that the settings for <?php echo APP_NAME;?>
|
|
(detailed below) are set up for optimal, reliable performance.</p>
