I upgraded to PHP8 and got this error on each page that displays a View

[12-Jan-2022 08:29:59 UTC] PHP Fatal error: Uncaught ArgumentCountError: array_merge() does not accept unknown named parameters in /home/434097.cloudwaysapps.com/fezrenmkqw/public_html/wp-content/plugins/wp-views/embedded/inc/classes/wpv-cache.class.php:358

Hello. Thank you for contacting the Toolset support.

Currently Toolset is not fully compatible with PHP8.

We already added note about that on our requirements Doc:
=> https://toolset.com/toolset-requirements/
- Important notes:
-- PHP 8 is currently not supported due to some issues. We’re working on fixing this. In the meantime, please use PHP 7 version.
-- While Toolset works with PHP 5.6+ and MySQL 5.6+, they reached the official End Of Life, and are not recommended for security and performance reasons.

I suggest you can downgrade the PHP version and try to resolve your issue.

I indeed just found the same article. It surprised me that Toolset is still not PHP8 compatible as 8 has been around some time now. Downgraded the server to 7.4 and the pages with the views are working again.
