Issues with PHP 8.0? [RESOLVED]

Just migrated to Kinsta and set it to use PHP 8.0 - then the quiz stopped working with a fatal error being triggered. I downgraded the server to PHP 7.4 and the quiz works fine again.

I thought the Quiz was working with php 8? Trying to determine if this is an issue with the add-on or the host?

Figured I would try here to see if others are using this on 8 with no issues?

Have you tried manually updating to the latest build of the add-on, available from the downloads page?

Once updated you’ll also need to clear/flush any caching and/or script optimization plugins and/or services the site is using as well as your browser cache.

Thanks I will try that, but I am on the latest version of the add-on already…

Looks like there were a couple of files missing from the migration! Thanks and sorry to bug you with this! All is good.
