Hello guys , i have an issue of my website .
When Add a new item to cart and go to homepage or any-other page the cart goes to be 0 and when go product page the cart refresh again ..
i tried everything i could
1- turn the host cache off
2- clear cpanel cache
3- clear opencart admin cache
4- restore htaccess to default
5- clear browser cache
nothing helped me out .
i didn't install any new extensions
i use journal 3 theme
opencart 3.0.3.2 latest version
my website link e-electra.com
please help me
sounds like a browser cache issue.
open chrome developer tools->network->disable cache and try again.
if the issue is gone, you are not sending the correct caching headers to the browser.

A site on OC1.5.5.1 had a similar issue.
Turns out we were moved onto a Varnish server - absolutely wonderful for speed, but nothing we tried made it useable for a cart. It is supposed to work - we didn’t find anything for opencart, but there is info about it for wordpress ( for example - https://docs.easydigitaldownloads.com/a ... th-varnish) - None of these worked, at least not a few years ago. Finally, we move off the varnish server and voila - worked ..

well, in any event, the cache control header is wrong, cloudflare and litespeed may also have a part in it.

@Zezoiaj your welcome although I had to laugh ..
@letxobnav thank you for that - may I pick your brains on that please. How would you set that up specifically for the cart dropdown OC3.0.3.2 for example?

well, you basically do not want anything produced by the response class to be cached, not in a proxy and not in the browsers.
So you could send no-cache headers on each individual page and each individual ajax call result like the cart info popup but you might as well set those headers in the response class itself in framework.php
would become
that will prevent caching of output produced by response, including ajax call results, so it will not affect other assets like js,css,images which go via expire headers etc.
On a side note, if you install 3rd party cache extensions which circumvent the standard response class or start caching after that class has produced it output or starts sending cache headers that override previously send cache headers, then all bets are off.
Journal themes seem to have a knack for over-caching to compensate for their poor performance due to their bulk designs.

Code: Select all
// Response
$response = new Response();
$response->addHeader('Content-Type: text/html; charset=utf-8');
$response->setCompression($config->get('config_compression'));
$registry->set('response', $response);Code: Select all
// Response
$response = new Response();
$response->addHeader('Content-Type: text/html; charset=utf-8');
$response->addHeader('Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0');
$response->addHeader('Pragma: no-cache');
$response->setCompression($config->get('config_compression'));

I see that electera is using cache-control: public, max-age=1 which states that anybody may cache this page even shared caches but only for 1 second.
That works as well.
