How Do I Resolve A Notice re. "Add Object Deprecated"


I'm not sure if you can help me with this issue, but I hope you can at least provide me with some direction as to what it means and how to go about fixing it.

After installing the latest upgrade provided by, I received the following notification and am unsure how to resolve it.

"Notice: add_object_page is deprecated since version 4.5! Use add_menu_page() instead. in /home4/wsbydesi/public_html/ on line 3658"

Can you help shed some light on what the notice is trying to tell me to do to resolve the issue and exactly what "add_object_page" is?

I really appreciate your help.
