I am not very happy with this answer. I know you guys work hard trying to help everyone out but I do pay for these and I would like to hear something other than the fact that I need to go and spend more money to get the site to work. I am not the most educated developer but I have been doing it long enough to know that if I continue to updated, that I will in time run into issues. However, this is not just a simple little issue. The whole site is broken.
Granted, I have not updated in quite some time so if I need t go back and update incrementally than I will but I am guessing that is not an option at this point nor is it probably a solution to my current issue.
So I am still requesting help on how I would go about doing this since I made the changed that you suggested and turned on the correct Stack but now the whole site is broken except for the header. What do i do about that? you never said anything about replacing the old child theme with the most current one. Not sure what that will do either. I need your guidance on that.
Lastly, when I go into CUSTOMIZE, I am getting an error that I have no idea how to resolve and would expect that you can go and take a look and let me know more specifically what I need to do as the error itself is VERY brad scoped. (see attachment for error)
Many thanks,
Houston
