invalid token error
 

A lot of my members including myself are getting the below randomly when posting a new thread or replying to a thread

When I try to start a new topic, I get an error: "Invalid or expired token."

Running 4.2x

I even uninstalled about 10 plugins completely, ran maintenance and diagnostic. Everything is good there. Anyone have any ideas?

If you create a new style with no parent and use that, do you still have the problem?

As Kevin suggested, this is usually a problem within the template/style. So, create a new style with no parent and have the users use that style and see if they still have the same problem.
