There is a problem with the database structure

This article applies to CSVI VirtueMart 1.5 and higher

When opening CSVI VirtueMart you see the message:

There is a problem with the database structure

or when saving a template you get the message:

There was a problem storing the data: TableCsvi_templates::store failed - Unknown column 'template_id' in 'field list'

This indicates an upgrade has been done from CSV Improved 0.9 to CSVI VirtueMart 1.5 or higher but the upgrade was not successful.

If you have no templates to preserve do the following:

1. Uninstall CSVI VirtueMart
2. Go to PhpMyAdmin and drop all the tables starting with jos_csvi_
3. Install CSVI VirtueMart

That should clean everything up.

If you have templates to preserve do this:

1. Uninstall CSV Improved
2. Install CSV Improved 1.5 converter
3. Uninstall CSV Improved 1.5 converter
4. Install CSVI VirtueMart
