Divi Theme – Fatal Widgets crash

Hi,

I have recently updated PHP. From like 5.6 to 8.2. Naturally this has caused a few issues.

I have managed to trace them back to the theme Divi. Which the whole website was built with years ago. Something to do with the widget module is causing a PHP Fatal error.

[03-Jan-2024 08:27:55 UTC] PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function WP_Widget::__construct(), 0 passed in /home/rsta/public_html/wp-includes/class-wp-widget-factory.php on line 62 and at least 2 expected in /home/rsta/public_html/wp-includes/class-wp-widget.php:163

I have managed to get the site partly working by disabling the 3 files

• widget-about.php
• widget-ads.php
• widget-adsense.php

I have noticed that the menu doesnt work anymore like it used to. Also the map widget just shows code and a few of the pages seem blank. Possibly because its full of widgets. Does anyone know how to fix these issues?

Thanks
