Please try to install CSV 2 POST from WordPress.org by going to Plugins --> Add New and searching "CSV 2 POST". This is safer and quicker than any other methods.
If your WordPress installation is on a path that includes "csv2post" it will trigger debugging to activate. This is meant for localhost development and can be disabled.
Your CSV file should be uploaded using FTP or WordPress itself. Submit the path to CSV 2 POST, CSV 2 POST does not handle the upload. I have left this independent because there is security to consider for a lot of .csv files and the user should decide where best to store the file.
Please ensure wherever your .csv file is stored that WordPress has permission to access the folder and file. Permissions can be changed in your hosting control panel for a directory. Developer software such as PhpED also allows it.
