PHP deprecation warnings

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is encountering PHP deprecation warnings related to the creation of dynamic properties in WooCommerce when editing products. These warnings appear specifically when the WPML plugins are activated.

Solution:
If you're experiencing similar PHP deprecation warnings, we recommend the following steps:
1. Ensure you have a backup of your site.
2. Temporarily disable all plugins except for WPML and WooCommerce, and switch to a default WordPress theme to check if the issue persists.
3. If the warnings disappear after deactivating other plugins and themes, it indicates a possible conflict with other installed extensions or the theme.
4. The issue has been identified as related to PHP 8.3+ versions, and a fix will be included in upcoming releases of the WPML plugins, specifically versions beyond 5.5.2.2.

Please note that these warnings are not indicative of functional problems with your site but are meant to inform about deprecated practices. If this solution does not apply or is outdated, or if the problem persists, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If needed, do not hesitate to open a new support ticket at WPML support forum for further assistance.

This is the technical support forum for WPML - the multilingual WordPress plugin.

rhettY	Hi, I have a staging site, and you can test. The warning is recorded while editting product. Not sure if it's related to WPML. When I edited a simple product, the error notice appeared, and then I translated the new content, more same notice appeared.

Dražen Supporter Languages: English (English ) Timezone: Europe/Zagreb (GMT+02:00)	Hello, thanks for getting back. Great, then please can you disable WPML plugin and test by editing simple product. As I can see from the first shared image, it does not seem to be coming from WPML plugins. Also shared WP forum implies issue is with custom code and Bricks theme. If the issue still happens when WPML is disabled then it is not something related to WPML products and something we can from WPML support help with. Let me know how it goes. Regards, Drazen

rhettY	Yes, I deactivated WPML plugins and editted the SKU in an variable product and a simple product: variable: hidden link simple: hidden link No error. I activated WPML plugins, and re-editted the SKU.

Dražen Supporter Languages: English (English ) Timezone: Europe/Zagreb (GMT+02:00)	Hello, you mentioned before you have staging site. Can you confirm shared website is staging site and it is safe to disable plugins / themes and do some debugging? I would also need FTP access credentials. Thanks, Drazen
October 21, 2025 at 6:34 am #17501440
rhettY	Yes, the share site is a staging site. The live site is running campaign. We can't do test with it now.

Dražen Supporter Languages: English (English ) Timezone: Europe/Zagreb (GMT+02:00)	Hello, I’ve checked, and it appears the issue is related to PHP 8.3+ versions. We’ll be addressing this in one of the upcoming releases. Please note that it shouldn’t cause any problems with your website or WPML functionality — it’s just a warning message, not an actual error. Let me know if that works for you. If not, we can revisit this in a few days and test again with the new version of WCML, which will fix several messages and may also resolve the one you’re seeing. Regards, Drazen

rhettY	I just upgrade "WPML Multilingual & Multicurrency for WooCommerce" to 5.5.2.2. Do you mean this update?
October 22, 2025 at 5:31 am #17505008
Dražen Supporter Languages: English (English ) Timezone: Europe/Zagreb (GMT+02:00)	Hello, no, there will be 5.5.3 soon released and later version also, like 5.5.0 etc., that will fix this issues, as they are not error message just a warning, so it does not affect your website functionality.
