After doing some work recently for a client, I discovered that I needed to make some modifications to a plugin for WordPress called SplashScreen.

To be honest when I wrote the fix I did not realise there was a new version released, however I have found out that my fix still provides features I need.

For those that are looking to permit bots and search indexers to access your site using the SplashScreen plugin modify splashcreen.php to reflect the following updated function:

function display_splash() {
 function isBot() {
 $user_agent= array("bot", "ia_archive", "slurp", "crawl", "spider", "Yandex");
 $count = 0;
 foreach ($user_agent as $substring) {
 $count += substr_count( strtolower($_SERVER['HTTP_USER_AGENT']), $substring);
 }
 return $count;
 }

 global $splash;
 $bot = isBot();
 $splash->getSettings();

 if (($splash->allSettings['splashscreen_enable']) && (!is_admin()) &&
   (!$splash->is_excluded_url()) && (!isset($_COOKIE["splash"])) && ($bot == 0)) {
 // display the splash screen
 $dir = dirname(__FILE__) . '/';
 @include_once($dir . $splash->allSettings['splashscreen_type']);
 exit();
 }
 }
}

The benefit this has over the newer version is that you can still use an entirely separate page.

Hope it helps someone else.
