Has anyone experienced any difficulties with getting the forums to operate correctly on WP Engine? We have a site on there, and the forums work fine on their staging server, which has caching disabled completely, but no new posts can be made on the production server, which has a custom caching setup on it. We asked them to disable caching on the following directories so far, which they have, but it has not seemed to help:
/forum/
/wp-content/sp-resources/
/wp-content/plugins/simple-press/
Anything else we should try? Thanks.
