hi @kurund, would it be possible to upgrade civix and tag a new release for PHP8 compatibility? https://civicrm.org/blog/bgm/php-8-support-civicrm-extensions
I had to remove the "reviewed" status of the extension for now, so that people do not break their CiviCRM installation. I will add it back when it's fixed. https://civicrm.org/extensions/simple-donate
