Hello. Thank you for contacting the Toolset support.
The error you shared is a PHP notice that will not stop execution of your site.
However - I see you are using number of third-party plugin. In order to minimize the cause of the issue and to ensure there is no conflict with the plugins/theme you use:
Could you please try to resolve your issue by deactivating all third-party plugins as well as the default theme to check for any possible conflicts with any of the plugins or themes?
- Do you see any difference?
No other plugin or theme is going to change code in WooCommerce Views where you access product fields the outdated way noted in the warning message. I didn't send this looking for a fix for a current problem. I am worried that WooCommerce may remove support for this kind of access instead of just issuing a warning at some point in the future and I'd like to know if Toolset is working to update your code so that sites are not broken when / if that happens.
I do not see any other user reported the issue as well as I'm not sure on what page/post and with what configuration you get that PHP notice.
I'll keep eye on this notice and if any other user reported the same notice I will check with our concern team what steps we will require in order to fix this notice.
If you can share details on what page/post I can see the notice and with what configuration it would be great.
I have set the next reply to private which means only you and I have access to it.
