Hi – sorry you’re facing difficulties here.
One thing you might be able to try is simply changing the template from Default Events Template to Default Page Template (via the Events > Settings > Display admin screen).
If that doesn’t work, though, flip back to Default Events Template and follow the steps in our themer’s guide for setting up a custom tribe-events.css stylesheet – then add the following rule:
.tribe-events-page-template .site-main:before { position: static; }
There are probably still going to be a number of things to tidy up here, but that should in the main get you on track and at least make the event content visible.
Do either of those approaches help here?
