Serves cached 'unlogged' version even after logging in.

Hi,

I have an issue with the plugin that i’m not able to figure out. I have both browser and page caches setup. Every now and then this glitch happens:

– I go my live site, login and then i see my login username on top right and everything looks fine.
– I browse a few other posts and notice suddenly for some pages the login info on top right(name and profile pic) has gone and it serves a ‘cached unlogged in’ version of the page.
– Only if a hard refresh do i get the page with my logged in info.
– Again another post/page it may repeat.

I have caching disabled for logged in users, so i don’t know what the problem is.

Any help please?
