Hi Glyn!
We’d be happy to help — but I do want to note that our pre-sales forum is used to answer questions about purchasing our premium plugins.
If you’re looking for technical support, it would be awesome if you could post your question to our WordPress.org support forum.
Or, if you already have an active license for one of premium plugins, will you please log into your account and post your topic to our premium support forum instead?
In the meantime, I would suggest checking whether you have other published pages that are called “Events” or that use /events in the URL and, if so, delete them. You may also want to follow the steps in this post to get started.
Thanks so much!
Geoff
