All-in-One Event Calendar plugin by Time.ly crashes my website

The website appears blank.

We discovered that the error_log file had thousands of lines and was over 6.5 GB in size… finally, we managed to delete it, but it immediately started growing rapidly again.
This occurs when All-in-One Event Calendar plugin by Time.ly is enabled. (It turns out it has been deprecated since August 2025).

The calendar is an important element of our website, and the events contain a lot of information we need to preserve.

How can we restore functionality, even temporarily?
Is there another similar (and reliable) plugin to which we can migrate the events?

Thanks folk
