Conflict with Wordpress Object cache

[sepehr-davarnia]

Hi

Whenever I enable any of WordPress object caches (redis, memcache, memcahced, ...) OpenID connect throws this error.

@sepehr-davarnia I personally use a Redis object cache on our Development & Testing instances, as well as some client sites, and I have yet to see an issue. Are you certain that you are correctly configuring your object caches?

This is a problem for me too. We have a login button on every page, which generates the same state value with the cache enabled, leading to invalid state, though the issue only appears intermittently. Turning off the page cache completely is the only solution that we've found works.
