Deleting Calendar cache killed my calendar

Hi Time.ly

This issue relates to a free version running at https://www.pylonwebdev.co.uk/haseltine/calendar

I was trying to change the background colour of upcoming footer widget for todays date in theme options but it wasn’t displaying on the front end on refresh after killing browser cache.

On inspecting in Chrome, the colour was referencing a css file in https://www.pylonwebdev.co.uk/haseltine/wp-content/plugins/all-in-one-event-calendar/cache

I deleted the contents of this folder (not Twig folder though) and it has killed my calendar! I’ve restored the contents of the folder from a backup from 3 days ago, but the calendar is still messed up
properly.

What do I need to do to get it back to how it was?

Regards
