Good evening Daragh and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the issues you are experiencing on your calendar.
I would love to help you with this topic.
As a first troubleshooting step, could you please provide us with your complete system information in a private reply using the instructions found in the following link?

Secondly, I went on your website and I am not sure what your issue is.
I tried navigating to the next month (November) and the previous month (September), without any issue.
Could you perhaps send me a screenshot of what the issue is on your end ?
As a side note, it seems like you have a Javascript warning on your page “You have included the Google Maps API multiple times on this page. This may cause unexpected errors.”. You might want to look into that.
Best regards,
Geoff B.
