Hi, and thanks for your help.
I am using the "Placester real estate builder" plugin with the "Scribe" Up Front theme.
The Placester plugin is preventing any other widgets/plugins/shortcodes from appearing correctly.
The Placester plugin does display a message: "function WP_List_Table::get_columns() must be over-ridden in a sub-class."
I don't know how to "over-ride in a sub-class". Can you tell me how to perform this request?
The Placester plugin is critical to me. If I can get the Up Front themes to work with the Placester plugin, I can move dozens of clients to your platform.
