The plugin still works on my personal site.My personal site is running PHP 8.1.14 with WP 6.1.1. Using the Twenty Twenty-Two Theme. It’s a very minimal portfolio and blog site.The site I am working on, which is having this fatal error:This site has been around for a few years, using a paid-for theme and page builder (Impreza) with quite a few plugins. It’s been passed down through several SEO agencies that have just piled on more and more plugins.I have now copied this to a staging site and ripped it all down, rebuilding it with the Twenty- Twenty-Three theme. Keeping everything pretty vanilla with minimal plugins. This staging site is now updated to PHP 8.0, using WP 6.1.1.This staging site is where the fatal error is now occurring when attempting to install.The original plugins are still installed but deactivated. Woo Commerce is enabled.I have attached an image of the plugin list. * ![](https://i0.wp.com/bchp2stg.wpengine.com/wp-content/uploads/2023/03/screencapture- bchp2stg-wpengine-wp-admin-plugins-php-2023-03-08-16_11_29.png?ssl=1) * Plugin Author [Phi Phan](https://wordpress.org/support/users/mr2p/) * (@mr2p) * [3 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-when-installing-22/#post-16541690) * Thank you very much [@bchpdigital](https://wordpress.org/support/users/bchpdigital/) for the details. I still don’t know you get this error. The patterns file is still there in the repo [https://plugins.trac.wordpress.org/browser/content-blocks-builder/tags/2.3.9/includes/patterns.php](https://plugins.trac.wordpress.org/browser/content-blocks-builder/tags/2.3.9/includes/patterns.php). Can you double-check whether the file exists in your installation or not? It should be located at “wp-content/plugins/content-blocks-builder/includes/patterns. php”. * I think for some reason, maybe the file is missing in your first installation, so can you please remove it completely and re-install it again? * Phi. * Thread Starter [bchpdigital](https://wordpress.org/support/users/bchpdigital/) * (@bchpdigital) * [3 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-when-installing-22/#post-16542950) * Hi. Thank you for looking into this. The patterns.php file is there, in the location you have specified.I’ve deleted the plugin in WP, and deleted the “cotent-blocks- builder” folder with “wp-content/plugins”.I’ve reinstalled the plugin again and I’m still receiving the same error. * Plugin Author [Phi Phan](https://wordpress.org/support/users/mr2p/) * (@mr2p) * [3 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-when-installing-22/#post-16543021) * [@bchpdigital](https://wordpress.org/support/users/bchpdigital/) If you don’t mind, could you please allow me to access to your admin site? or could you please setup a test site on [https://instawp.com/](https://instawp.com/) with the same theme, plugin on your current site and grant me admin permission. * Phi. * Plugin Author [Phi Phan](https://wordpress.org/support/users/mr2p/) * (@mr2p) * [3 years, 3 months ago](https://wordpress.org/support/topic/fatal-error-when-installing-22/#post-16543082) * [@bchpdigital](https://wordpress.org/support/users/bchpdigital/) Could you please send me the Site Health Info for your site?

I don’t know these are interfering.I’d be happy to give you access to this dev site. A vanilla install that gives me the same error when I try to install your plugin.If you would provide me with an email address, I will send you a login.
