I am using w3 total cache, and only few of its functions are on - browser cache, page cache. Yet when someone tries to login, seems like they have the homepage or other pages cached because they have visited them few minutes ago, and if after loging in they try to visit the same pages they appear logged out, unles the refresh the page.
The loging itself works, but it's not visible for the browser until refresh. Do you have any suggestions to which cache might be connected. Because I use the cache to speed up the website and so I need it, but if users keep complaining, I might need to turn it off since I don't want to lose the visitors.
