The problem is that you're using an old version of the PDF invoice plugin, which isn't compatible with PHP8: [ www.hikashop.com/marketplace/product/18-plugin-pdf.html](https://www.hikashop.com/marketplace/product/18-plugin-pdf.html) You need to download the latest version of the plugin on our website and install it on your website and it will automatically fix the problem.

Thanks")* Thank you - but it won't install - the Joomla rotating busy symbol keeps going for hours and it never comes back or completes. I used I uploaded the .zip file that downloaded from the email link that is in one of the purchase emails. Pity there's not a discount for upgrading this plugin - I had to pay the full price to get the upgrade. Thanks for any help on the Install issue.
