I have made a product import using Magmi with no errors on the import side.
Every product is a simple product that has 2 attributes of type checkbox that adds some options and increases the price in a manner that looks a little like this:
Product price 50,00
[ ] add packaging +1,50
[ ] add custom note +1,75
After this everything looks good except for the fact that the price is not shown in the page. I have checked for a price mapping and it is deactivated so this is not the issue.
Another strange behavior is that if I open in magento admin any product and save it (without changing anything at all) it is working correctly.
I have also tried a bulk attribute change from magento administration and after that saving all products at once bu it proved not to work.
Reindexing and cache building did not prove to solve the problem either.
Magento is 1.6.2.0 Community edition.
