On a 1.5.1 Magento store,With SCP extension installed for configurables products, we have an error that shows when saving a configurable or simple product (in backend=> catalog)
the error is : SQLSTATE[21S01]: Insert value list does not match column list: 1136 Column count doesn't match value count at row 1.
On the same time, on frontend, some configurable products with a price to 0 are shown as special prices, even if the price in backend is different : [url removed, login to view]
I have no possibility to reindex data for prices in backend.
This project is only dedicated providers with a Magento experience (I will have a look to your old jobs)
