Fatal error with PHP 8 and WooCommerce

Uncaught ValueError: Unknown format specifier “a”

You have a wrongly formatted translation value. Something like “%a” in your translation would be invalid and should probably be “%s” (or similar)

This is explained in detail in the following FAQ: https://localise.biz/wordpress/plugin/faqs/printf-errors

When deactivating Loco Translate, everything is back to normal.

Presumably because the bad translation is not loaded without Loco Translate being active. This suggests it is in your own custom translations.

Hi Tim,

Thank you for your reply!

I look at each translation file manually and no “%a” is showing up.

The incriminated line is this one:

<span class="displaying-num"><?php echo esc_html( sprintf( _n( '%s item', '%s items', $variations_count, 'woocommerce' ), $variations_count ) ); ?></span>

from: https://github.com/woocommerce/woocommerce/blob/1d4888768f4f56553ab951a5310cb9489de29257/plugins/woocommerce/includes/admin/meta-boxes/views/html-product-data-variations.php#L96

I could not see what is wrong here, any idea?…

Thanks in advance, best regards,

There is nothing wrong here. As explained – it’s a bad translation, not a bad bit of code.

The “%a” is somewhere, because the error is telling you so. I can’t tell you where it is, except that it sounds like it’s in a custom translation file, as opposed to an installed one.

Hello there,

I have the same issue with php 8.1….

Hello, same error here with php 8/8.1

I need to disable the plugin to make it works.

How to resolve this ?

Here’s my error :

WordPress version 6.1.1
Extension actuelle?: WooCommerce (version 7.3.0)
PHP version 8.1.11

Uncaught ValueError: Unknown format specifier “a” in /public_html/wp-content/plugins/woocommerce/includes/admin/meta-boxes/views/html-product-data-variations.php:106

Hello,
I have the same problem.
I know it’s not the best solution but if you replace

_n( '%s item', '%s items', $variations_count, 'woocommerce' )  

with

"%s articles"

The product page with variations work fine. (My admin is in french).

_n don’t return the good string. It must return the traduction “%s articles” but it return “% articles”.

Hello,

Thanks a lot, I could make variations work back in the admin.
I don’t have any translation plugin, so I wonder what plugin (maybe the theme?) is interfering.

Theme is Negan (last update from them is december 22), and everything is up-to-date.

I don’t think the problem is the theme. I use another theme and i have the bug. What is your admin language ?

sorry for the late reply, didnt get any notification I believe.
the admin is in french

I specify that the variations worked for years, the bug is new (5/10 days ago)

Same for me, variations work for years.
My admin is also in french.

I have other website with woocommerce and variations with french admin and i don’t have this problem.
Very strange.

Hi I had the same problem and delete the “language” folder and re-download via updates solved the issue

Merci Jean!

One more thing, can you please be more precise with

re-download via updates

Thank you Jean, i test and it’s OK!

@rollyourz you need to replace this file : /wp-content/languages/woocommerce/woocommerce-fr_FR.mo

See this page : https://woocommerce.com/document/traduction-et-localisation-de-woocommerce/#section-3 (in french)

Thank you Jean, i test and it’s OK!
