Almost certainly some of the previous mods configuration values are still there.

Search the configuration table for configuration_key = "MAX_DISPLAY_XSELL"
And delete this entry.

While you at it see if "MIN_DISPLAY_XSELL" is also there and delete it as well
I deleted everything, and I got fresh installation. I don't know why only old products can be crossselled. Any new products added cannot be crossselled.

All my model numbers are unique, so I don't have any problems with the model numbers.

Please give me advice regarding this issue. Thanks so much for your help and support.
