Hello seattledog,
Thanks for reaching out to us!
As an initial step, verify that the License key for the Filter Bar plugin has been added to the site. You can check that by going to Events -> Settings and the going to the Licenses tab. Once you’ve made sure it’s added, you can go back to the Updates page under the Dashboard tab and click the Check Again button to manually check for updates.
If that doesn’t work to show the update, you can manually update the plugin by downloading the zip file from your account at http://tri.be and then uploading the files via FTP.
Let me know if this helps.
Thanks!
