Hello Alexander,
Thanks for reaching out to us!
I notice the title missing on your site as well as the site title not showing after the “|” when switching months on the calendar. However, I wasn’t able to recreate the issue locally.
To start with, have you followed the steps in the Testing for Conflicts procedures to see if this is a potential conflict with another plugin? Particularly, there may be some SEO settings within your theme or an SEO plugin that may be causing this issue.
I’m sorry I wasn’t able to give you a direct response but hopefully we’ll be able to get you pointed in the right direction.
Thanks!
