My blog has some strange behavior which I have tried so many ways to solve it but no lucks...
Some users report that when they log on and browse the blog, it keeps asking them to log on again as if they have not done so. Sometimes it seems the browser does not update the new data and they have to manually press F5 several times.
My blog uses a plugin that manage membership. Some users report that they can log on successfully but the cannot see member-only content (set by the plugin). The way around this is for them to throw any comment on the page. Then the problem goes away.
I have tried changing three memebership plugins for three vendors but same problem persists. I have tried deactivate all plugins and reactivate them. I have even tried moving to a new hosting company. But very strangely, the problem still persists.
