After playing around I wanted to generate another project with an existing table (reuse of Step 1 Your data).
So I delete the project and start a new project.
I select the database from the old project and select "reset table"
the following error comes:
Fatal error: Call to undefined function csv2post_sql_reset_project() in /kunden/73538_60386/schiener/wp-content/plugins/csv-2-post/templatesystem/include/csv2post_form_processing.php on line 2431"
