Problem with login sidebar when WP Rocket page cache is activated

Hello, the sidebar works in a bizarre way if wp rocket page cache is activated.
I’ve tried to contacted the wp rocket support, they say that:
“1) Regarding the login / logout links in your upper menu, are these being generated and updated using PHP? If so, then that makes them incompatible with page caching.

That’s because WP Rocket converts all of the PHP and MySQL processes on a given page into static HTML output instead (as do most page caching plugins) — which means a PHP-based login / logout link on any page which has already been cached won’t be updated again until the cache is cleared.

For an explanation of how page caching works, you might find this post useful:
http://blog.wp-rocket.me/wordpress-page-caching-explained-in-plain-english/

One way you could test to see if the problem is definitely related to the page caching would be to temporarily install and activate the helper plugin from this article:

Disable Page Caching

If the problem with the login resolves after that, then you’ll know these links are not compatible with page caching.

Dynamic login links must rely 100% on AJAX / JavaScript to be protected from the page caching — otherwise, they can only be updated when the cache is cleared.”

You can check the issue in the video.
This issue is reproduced in this way:
1) enter in the site.
2) close the browser.
3) reopen the browser and enter in the site.

It seems that the first cached page served after reopening the browser is not friendly for login sidebar.

Hello,

We checked your video but we don’t see anything wrong there. Could you please send us step-by-step instructions about how to reproduce the problem?

Kind Regards

Frontend behaviour
Current situation:
1, open the site and consent the cookie.
2,click to open side bar and digit credentials
3, click “Login”
4, after that the page is reloaded click the login/registrati to reopen the sidebar.
5,insert credentials FOR ANOTHER TIME in the sidebar and click “Login”
6, user is finally logged in with success.

The ideal one:
1, open the site and consent the cookie.
2,click to open side bar and digit credentials
3, click “Login”
4,user is finally logged in with success.

The problem is that user cannot login with success in the first time that he enters the credentials. This issue can be reproduced if the page cache is enabled.
in fact, on the page which is not cached( for exemple wishlist), there isn’t this problem.

Please check the site.

Please, send the username and password that you use for the test so we can reproduce it.

here are the credentials

Please, send us your FTP access so we can troubleshoot this problem further.

Hello,

Try to add the following PHP code snippet to the child theme functions.php file to fix this

add_filter(
	'init',
	function() {
		if ( isset( $_REQUEST['woocommerce-login-nonce'] ) ) {
			$_REQUEST['woocommerce-login-nonce'] = wp_create_nonce( 'woocommerce-login' );
		}
	}
);

Hello, thank you for your work, the error is not showing any more on the site.
But I have 2 doubts:
1, Isn’t the upsell section in the cart page is a carousel? Because I’ve setted 8 upsell products for a single product, on the mobile both of them are shown with carousel, but on the desktop only the first 4 is shown and there isn’t possibility to see other 4 items.
2, What was causing the error that you’ve fixed?

Hello,

The problem is still not fixed, unfortunately. It looks like something on your website sanitize the script and remove && signs. Try to temporarily disable all external plugins so we can check what is wrong there.

Kind Regards
