Error: agenda-buttons.twig does not exist

This plugin has been giving me a problem in the last 2 weeks.

Here is the error message (admin dashboard):

`All-in-One Event Calendar has been disabled due to an error:
The specified file “agenda-buttons.twig” doesn’t exist.
Toggle error details Try reactivating plugin`

`Error Details:

Request Uri: /calendar/action~agenda/page_offset~-1/cat_ids~75,8/request_format~json/`

It got fixed everytime I clicked ‘Try reactivating plugin’ but I do not want to keep doing it.

Please advise.

Thanks!
