I've attached few snaps to get idea.Hi All, I have installed opencart 3.0.3.8 version recently and I'm facing this problem - whenever i try to click on add to cart button, its adds the product in cart but when i move to next step i.e. checkout page - the cart becomes empty. When i click back button , the cart still shows that 1 product which I added. For resolving the issue, i again freshly installed opencart 3.0.3.8 , It was working fine however i faced new issue where it was showing error "warning - shipping method required" in shipping details section of checkout page. The current state is sometimes it shows empty cart issue and even if it lets me to fill first 2 steps of checkout page , it shows shipping method issue. May i please know what is the problem and how to resolve it? I'm beginner at this . Please help me! I've attached few snaps to get idea.

You may be able to test by using your web browser's developer tool to disable the cache.
The easiest way to fix the lack of cache control headers issue is by making the following change to the framework.
In system/framework.php find the following line at around line 74.
After that line add the following.
Note, using header() rather than $response->addHeader() as the later doesn't apply to redirects. I've noticed recently that Firefox aggressively caches redirects, which can lead to some strange issues.
