In the past I bought the Fest WordPress theme and use it for an event website.
When I upgrade to php 8.0, the theme/website is no longer working.

If I buy a new subscription and download the newest version (1.8) of Fest, is this version then working with php 8.0?

Thanks in advance!

The errors I see when using php 7.4:
