I have a site that in the hub it shows that there is an update pending. If I click on it, the update fails with the error "Plugin is at the latest version" which is correct as the plugin is at the latest version, but yet it still shows that there is an update in the hub. I logged out of the account on the wp-admin dashboard of the site and then logged in again. This seemed like it worked but ten minutes later it was showing the update again. It is only with this site that the issue is occurring. I don't have any server-side caching going on. The plugin is the Really Simple SSL. Any ideas?
