Just installed the Events calendar plugin. All seems fine, managing is ok, but the problem is that the calendar view, event list and event page comes as a new pages, not keeping the sidebar and the rest. They just come up as separate page breaking all the template.
You can see the problem here http://www.festivali.lv/ Its the "Festivali drizuma" section. Try to click on event or View all links.
I didnot made any changes at all, just installed the plugin, thats all.
