I’m sure many Kinsta-WooCommerce developers have gotten this email from Kinsta:
Hi Kinsta User,
Obsolete PHP versions are replaced by more recent versions every year. PHP 7.4 is being replaced this year by PHP 8. As a result, we are discontinuing support for PHP 7.4. It’s critical that you update your sites to PHP 8 as soon as possible.
Our problem was that our sites were running hot and live, with many eCommerce orders. We didn’t want down time.
Thus, we tested over 55 WooCommerce / WordPress plugins for compatibility to Kinsta’s PHP 8.0 Upgrade. Here are the results of this huge project
Once we ran up against a plugin that wasn’t working well, we were able to remove it or find a good replacement.
If you have any of these plugins, you can see our manual testing results below for your own work:
