Hello Bartosz,
Thank you all for working to get the plugin fixed. The black screen issue is gone but the challenge of the extension names still exist.
The website is not pulling the name of the pages rather the page Ids. For instance http://www.mysite.com/calendar returns a 404 error but the http://www.mysite.com/?page_id=8235 returns the actual page.
Don’t mean to add extra pressure but is there any way to solve this?
