I do not have any idea how to get to the “wordpress file folder inside the htdocs of development server, to find the wp-content folder”
There is nothing resembling that on my WordPress dashboard and nothing that contains any code files with the exception of the Theme Editor.
If it cannot be changed with the Theme Editor, then it is probably well beyond the scope of my ability. You are going to have to supply much more detailed instructions.
It appears that this is a known bug, and it also appears this bug was introduced during the latest ColorMag update to Ver 1.4.8. What are the plans to fix it?
