close unreal, go into the project folder projectname\saved\webcache, and delete everything in there.

Thanks you so much!

Throwing a few ideas, this could be automated using C++, and support for a ā€œno-cacheā€ mode that does this could be made1

Do it yourself. Not that Hard. A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

Although I think deleting the directory programmatically is a good idea. I have found that calling either IPlatformFile::DeleteDirectory or IPlatformFile::DeleteDirectoryRecursively fails on the webcache folder because the game/application uses files in the directory while itā€™s running.

Hi,
After a lot of struggle, I was successfully able to clear the browser cookies from the game. A little bit of c++ coding will be needed in this case.

Add WebBrowser module in your build.cs file
Create a c++ class blueprint library
import the following classes

#include "IWebBrowserCookieManager.h"
#include "IWebBrowserSingleton.h"
#include "WebBrowserModule.h"

Make a blueprint callable function and paste the following code:

IWebBrowserSingleton* WebBrowserSingleton = IWebBrowserModule::Get().GetSingleton();
    if (WebBrowserSingleton)
    {
        TSharedPtr<IWebBrowserCookieManager> CookieManager = WebBrowserSingleton->GetCookieManager();
        if (CookieManager.IsValid())
        {
            CookieManager->DeleteCookies();
        }
    }

Call this function from your blueprint anywhere.
