I upgraded a client's site from V1.4 to V1.9. Everything is working fine now and as far as we can tell the number of orders is correct, the values of those orders are correct, but the sales values on the dashboard are much less on the new version. For example year to date sales on the old site are $150,000 and the YTD on the new version are $83,000.
Could there have been a table or field that didn't update properly that feeds the dashboard numbers but not the order list?
Have you tried reindex the data? If the process stoppes or "hangs" this can happend. If there is some tables or anything not working as it should, please check the logs and post it here.
I have reindexed all and it says that they are successful. Logs have been enabled but I see nothing in them.
