PHP compiling errors after install from ondrej/php repository

Hi, I’ve been using ppa:ondrej/php repository for many months, but today, after installing PHP 8.0 and 7.4 on a new fresh server, I noticed the following error:

PHP message: PHP Warning:  preg_match(): Compilation failed: unrecognised compile-time option bit(s) at offset 0 in <any_php_file>

This problem doesn’t occur with older versions of PHP (<=7.3) and have never occurred before. I tested on the latest versions of WordPress and Drupal. Anyone faced with a similar error recently?

Regards

Hello,

Does it happen for a specific plugin or just a plain WordPress installation?

I’ve noticed a similar discussion here:

https://wordpress.org/support/topic/php-warning-preg_match-compilation-failed/

The suggestion is that a plugin or a theme that you are using might not be compatible with the newer PHP version in question.

You could also try updating your packages with:

sudo apt update
sudo apt upgrade
