Hi @opialm,
Thanks for alerting us to this.
The PHP messages you have shared with us are PHP warning messages which are a built-in method of debugging that was added by WordPress for developers.
The purpose of these warning messages is to help developers debug issues with their code. Plugin and theme developers need this information to check for compatibility and best practices.
Fortunately, PHP Notices and warning messages such as these are the kinds of errors that do not stop WordPress, themes, or plugins from loading your website and thus cannot break your site, and so do not be worried about something like that happening.
With all of that said, the development team (@bradvin) has been made aware of this warning messages and will work on an update that will resolve the underlying issue.
Hope this clarifies this issue for you. If you have any questions, don’t hesitate to ask.
Kind regards,
Elvis.
