Cannot use output buffering in output buffering display handlers in Unknown

Hello,
I need you to please help me since I have problems when I query a records entered from Contact form 7 generated through a shortcodes with cfdb-table.
I have added unbuffered = “true” as the documentation indicates but it still does not work.
The error that is presented is “Fatal error: Unknown: Can not use output buffering in output buffering display handlers in Unknown on line 0 contact form db”
Thank you
