PHP 8.0 – FATAL ERROR

  • Resolved 100lba

    (@100lba)


    5 years ago

    Hi!

    Updated from 7.4 to 8.0 using latest version of WordPress and WooCommerce. I get this error:

    An error of type E_COMPILE_ERROR was caused in line 518 of the file [my-site]/wp-content/plugins/woocommerce/includes/class-wc-download-handler.php. Error message: Only variables can be passed by reference

    This has already been ‘covered’ in this thread but I don’t have the feeling that this relates to custom coding? I haven’t changed anything in WooCommerce php files.

    Hi there!

    The first thing we’d like to make sure of is seeing if this is a conflict. I understand that you don’t feel like this is related to custom code, but in order for us to pass this on to our development team, we do need to ask you to do a conflict test first.

    The steps for such a test are listed here: https://docs.woocommerce.com/document/how-to-test-for-conflicts/

    Looking forward to hearing back from you on what you find!

    Okay.

    So I’ve tried both (using WordPress Default Theme). No change. And also deactivating all plugins but WooCommerce. Same error.

    Hi there!

    Can you please take a complete backup of your store, uninstall WooCommerce, and then try installing a fresh copy that’s downloaded from here: https://wordpress.org/plugins/woocommerce/

    Also, can you please include the steps to replicate the error you’re seeing?

    Completed the steps. Same error even with fresh WooCommerce. As soon as I switch from PHP 7.4 to PHP 8.0 and reload the site, in backend as well as front end.

    Hi there!

    Thank you for testing that out for us.

    Could you please share a copy of your site’s System Status? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”.  Once you’ve done that, paste it here in your response.

    I understand PHP 8.0 gives you an error, so please share it when your site is on PHP 7.4.

    Hi there!

    Thank you for the System Status Report. I don’t see anything obvious with the System Status Report except for the templates overridden by your theme.

    Can you please share a screenshot of the same error you’re seeing, with just WooCommerce as the active plugin, and Storefront as the active theme?

    You can set up a staging site to test by getting in touch with your web host, or using a plugin. The WP Staging plugin is perfect for making a clone of your live site so you can set up a local development site. If you need help setting it up, you can find the step-by-step documentation here: https://wordpress.org/plugins/wp-staging/#description under “HOW TO INSTALL AND SETUP?”

    Thank you for the screenshot. Interestingly, we’re still unable to replicate this on our own test site with PHP 8.0:

    For further troubleshooting, can you please test this on a different hosting environment / a local installation of WooCommerce + WooCommerce?

    I’m afraid I won’t get to that anytime soon, sry. But maybe we can get user @dabevap, from the linked thread above, on board and see if there are any similarities between our cases?

    My hosting provider actually has a very modern setup. There will be a server upgrade at the end of May and in the course of that, a few adjustments – maybe by chance that will settle the issue.

    Otherwise, I assume that as PHP 8 becomes more widespread, I’m sure at least a few other users will have the same problem. Can’t imagine this being a particular edge case, as I use almost everything out of the box.

    Hey again!

    I’m hoping that the update to your hosting setup will allow this to work without issue.

    I would love to be able to trace this down further, but without being able to replicate this in any of our testing, it’s pretty difficult.

    If you have any additional info that might help us narrow this down, please let us know.

    Hi @100lba,

    We’ve not heard back from you in a while and we might soon mark this thread as resolved. Thus, we’re checking if you were able to try the above suggestion and if the issue was resolved.
