Hello, @voiddigitalbulgaria,
Firstly, I would like to inform you that on our test site, we have not encountered any errors or warnings of the nature you described. Therefore, I kindly request that you ensure both your theme and plugins are up to date on your site.
Secondly, please note that the message you encountered is classified as a warning rather than an error. Warnings, in general, do not pose any harm to the functionality of your site, so there is no need to be overly concerned about it.
Furthermore, you mentioned that you have already implemented some changes to address the warning. If you are satisfied with these changes, that is excellent. However, if you still have concerns, you have the option to revert back to the previous state on your site.
Additionally, it is advisable to confirm that you are utilizing the latest version of the theme and its accompanying plugins. In the event that you continue to encounter the same warning, please be reassured that there is no need for alarm. Simply verify that your site is working and displaying correctly.
If you require any further assistance or encounter any other issues, please do not hesitate to contact us.
