Hi – sorry you’re experiencing problems.
When you say nothing appears on the events pages that sounds like you are talking about the frontend of the site (ie, what the public see) – yet that seems to be working when I visit your site.
Can you confirm if this is actually a problem in the admin environment (and have you tried clearing any filters that may have inadvertently been set via the Filters & Columns box that appears above the list of events if so)?
