Conservative, progressive cache problems

If you checked out the previous problems here and here, and you narrowed it down in them, that you have the cache time on static and you aren’t using cache plugins, then you should open up this file:

\modules\mod_smartslider2\mod_smartslider2.php

It contains a fix, just it’s outcommented, because it caused errors in some websites:

/*
 * Joomla cache fix!
 *//*
$config = JFactory::getConfig();
$caching = $config->get( 'config.caching' );
if($caching === NULL) $caching = $config->get( 'caching' );
$app = JFactory::getApplication();
if($app->isSite() && ($caching == 2 || $caching == 1)){
 if(class_exists('NextendCss', false)){
 $css = NextendCss::getInstance();
 $css->generateCSS();
 }
 if(class_exists('NextendJavascript', false)){
 $js = NextendJavascript::getInstance();
 $js->generateJs();
 }
}*/

You should remove the comment from around the code:

/*
 * Joomla cache fix!
 */
$config = JFactory::getConfig();
$caching = $config->get( 'config.caching' );
if($caching === NULL) $caching = $config->get( 'caching' );
$app = JFactory::getApplication();
if($app->isSite() && ($caching == 2 || $caching == 1)){
 if(class_exists('NextendCss', false)){
 $css = NextendCss::getInstance();
 $css->generateCSS();
 }
 if(class_exists('NextendJavascript', false)){
 $js = NextendJavascript::getInstance();
 $js->generateJs();
 }
}

Clear the Joomla cache, and check our sliders in your website again.
