Hello,
Elementor is not yet compatible with PHP 8+ version. Please refer to the following document and consider being on a compatible version of Elementor.?
“Elementor’s Roadmap to Upgrade PHP Versions” – https://developers.elementor.com/elementors-roadmap-to-upgrade-php-versions/
By the end of the year, our plan is to further increase the minimum required version to PHP 7.4, while upgrading the recommended version to either PHP 8.0 or 8.1, depending on the usage data at the time of decision-making.
In 2024, Elementor will cease support for PHP 7.x versions entirely, elevating the minimum required version to PHP 8.0 or 8.1, based on the available usage data.
Please note that these plans are subject to change based on real usage data and WordPress’s support for older PHP versions.
Regards.
