Enfold seems to add cache-disabling headers

I have the same issue with Enfold theme (version 3.0.4), disabling all the plugins did nothing, changing theme solve the problem.
Looking at the results of a recursive grep command performed on the root of this particular wordpress instance it seems there are 3 “no-cache” strings in Enfold theme’s files:

[root@server v1.0]$ sudo grep -R "no-cache" ./
[sudo] password for root: 
./wp-includes/class-wp.php:		// If Last-Modified is set to false, it should not be sent (no-cache situation).
./wp-includes/functions.php:		'Cache-Control' => 'no-cache, must-revalidate, max-age=0',
./wp-includes/functions.php:		'Pragma' => 'no-cache',
./wp-admin/includes/ajax-actions.php:		header( 'Cache-Control: no-cache, must-revalidate, max-age=0' );
./wp-admin/includes/ajax-actions.php:		header( 'Pragma: no-cache' );
./wp-content/plugins/si-contact-form/captcha/securimage.php:		header("Cache-Control: no-store, no-cache, must-revalidate");
./wp-content/plugins/si-contact-form/captcha/securimage.php:		header("Pragma: no-cache");
./wp-content/themes/Enfold/config-layerslider/LayerSlider/classes/class.ls.exportutil.php:		header('Pragma: no-cache');
./wp-content/themes/Enfold/enfold/config-layerslider/LayerSlider/classes/class.ls.exportutil.php:		header('Pragma: no-cache');
./wp-content/themes/Enfold/enfold/framework/php/wordpress-importer/avia-export-class.php:            header("Pragma: no-cache");
./wp-content/themes/Enfold/framework/php/wordpress-importer/avia-export-class.php:            /*header("Pragma: no-cache");*/

Do you have any idea on how to prevent Enfold to send no-cache headers?

Hi, I did what you suggested, with the parent theme the headers are still there while they are gone the moment I switch to wordpress default theme (Twenty Fourteen).
Plugins were all disabled.

It took me a while but I found the solution to the problem.
For some reason when using Enfold (and also some other plugins/themes, like for example MainWP) some nasty headers get added to every HTTP response.
The solution was to edit php.ini configuration file and change the following two parameters:

session.use_cookies = 0
session.cache_limiter = public

This way I get no more no-cache headers and Nginx correctly cache pages.

Hi,

I have the same problem.
My host offers Varnish but it does not work with Enfold.

Its not in any plugins because if i switch to another theme (like twenty fourteen) the cache works fine.
But in Enfold (latest, no child theme) it shows
Pragma: no cache
and
X-Cacheable NO: Backend headers

I am not logged in, have no domain nor session cookies and trying incognoto mode in chrome.
I also added the two php settings in htaccess (because i have no access to php.ini).
I use apache.

Please help because this is really important.

Installing this extension will allow me to use varnish with Enfold:
https://wordpress.org/plugins/add-headers/

But i still think this is worth investigating.

I have been experiencing the same issue with our company website. We are using varnish in front of wordpress, but it doesn’t cache page content because of the no-cache headers.

GiorgioAldeghi’s answer about changing php.ini settings for session.cache_limiter = public gave me a hint as to the cause. The no-cache headers are being added by PHP as a result of starting a PHP session, as I can see in my headers that there is also a session cookie being set when it shouldn’t be:

curl -I localhost

HTTP/1.1 200 OK
...
Set-Cookie: PHPSESSID=j6pvq3vodd9nrl5a0tlkacvv86; path=/
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache
...

A session should definitely not be started for viewing normal page content when not logged in.

I did a grep search for session_start and found the culprits in avia related files:

$ grep -r -i –include \*.php session_start *
htdocs/wp-content/themes/enfold/config-templatebuilder/avia-shortcodes/portfolio.php: if(!is_admin() && !current_theme_supports(‘avia_no_session_support’) && !session_id()) session_start();
htdocs/wp-content/themes/enfold/config-templatebuilder/avia-shortcodes/masonry_entries.php: if(!is_admin() && !current_theme_supports(‘avia_no_session_support’) && !session_id()) session_start();

As you can see, the avia-shortcodes are starting a session if we are not admin and the current theme does not support ‘avia_no_session_support’ and we don’t already have a session.

The solution for me was to add the following to my child theme functions.php:

function custom_theme_setup() {
        add_theme_support('avia_no_session_support');
}
add_action( 'after_setup_theme', 'custom_theme_setup' );

But the real solution should be for Kreisi to fix this issue for the theme itself.

The sessions are used for the breadcrumbs so if you disable them then the portfolio breadcrumbs will not link back to the page where you used the portfolio grid shortcode on.

I don’t use the portfolio so that’s not a concern for me. I’m more interested in getting caching to work properly to make my site fast.

If i’m not using the portfolio shortcode, enfold shouldn’t be starting a session?

Elliot, I’m a bit confused because in this forum you can’t directly reply to a certain post

A session will still be created unless your using this.

Who are you responding to?

Can you confirm that adding the above code snippet will break portfolio breadcrumbs and portfolio breadcrumbs only?

Also I am curious why the session is started even on a page that is not using portfolios at all. This seems to be a bug.

never mind
