Hi
The new version has many core changes that require existing campaigns to be migrated properly. This does not happen automatically due to the nature of the plugin and a certain change that makes it more complicated in certain blogs.
If you have updated version 7 with version 8 on a live blog before testing then any posts already created using CSV 2 POST will no longer be managed by the plugin. That can be changed but the tool to do it is not ready. Most users do not update an autoblogging plugin once the campaign is running, to avoid upsetting an ongoing project. So we’re getting away with this so far.
If your situation is that your .csv file used to work with version 7 or before but no longer works with version 8 it will be due to headers. Version 8 focuses on running more efficiently in terms of PHP and requires the .csv file to have MySQL ready headers. It makes the code easier because we do not need to manage different versions of headers i.e. complex headers need to be simplified for use in the database which does not accept complex headers. That simply means no characters or spaces in your headers. Simplifying them makes them suitable to use in MySQL table names and makes the relationship between .csv file and database table easier.
If your still not sure and stuck please email [email protected] who is the author of the plugin. He has endless time for his plugin users.
