Tableau Public Error – Data Extract Required

I’m trying to load a workbook from Tableau Desktop into Tableau Public, but it keeps throwing an error stating:

“The Tableau server you are publishing to does not permit external database connections, Use the Data menu to create an extract for the following data sources.”

I went and created the data extract and I’m still getting the same error. Any help would be appreciated. Thanks.
