I noticed the following bug:
1. Visiting the event calendar via <URL>/events/
2. Changing the view to photo
3. The plugin will send you automatically to the first event category although no category was selected before (in my case: events/kategorie/allgemein/foto/
The bug seems to be in the php code where the URL is generated for the view.
Right now I manually strip out the categorie-filtering in the url manually in my childtheme (modules/bar.php), so you can’t see the bug on our production site. But I also tested it on a local fresh wordpress installation.
Cheers,
Matthias
