No caching option due to no cache issue

Hey Enfoldfanatic,
The two files that you mention are both export functions that only fire when the settings are being exported, the first one is when the LayerSlider export zip file is being created and the second one is for when the Enfold theme settings are being exported, in both cases you would not want the export to use cached files and neither of these run in normal site operations, so I don’t see how this could be an issue.
Please feel free to remove these lines with the no-cache but be aware the export features may not work correctly.
Also note that neither of these files can be added to a child theme so you will need to edit these files with each update.
If you feel that this really needs to be changed in the theme the Dev Team has opened a new Github Feature Request for users to place requests and follow them as the Dev Team reviews them.

Best regards,
Mike

Hi,
In my research I find that this is added by WordPress, and to remove it try adding this code to the end of your child theme functions.php file in Appearance ▸ Editor:

function varnish_safe_http_headers() {
    header( 'X-UA-Compatible: IE=edge,chrome=1' );
    session_cache_limiter('');
    header("Cache-Control: public, s-maxage=120");
  if( !session_id() )
  {
    session_start();
  }
}
add_action( 'send_headers', 'varnish_safe_http_headers' );

Best regards,

Hi,
Try the other solution on the same page:

add_filter('wp_headers', 'wpse167128_nocache');
function wpse167128_nocache($headers)
{
    unset($headers['Cache-Control']);
    return $headers;
}

or include an admin login so we can try.

Best regards,
Mike

Hi,
Glad that this helped, I don’t know of anything that has changed in the theme, and I have not seen any other questions about this.
Unless there is anything else we can assist with on this issue, shall we close this thread then?

Best regards,
Mike
