I just made a test order and the system wrote me : The total of your order is too high for all the possible shipping methods

what does it mean?

Hi,

It means that the total weight of your order is too high for the shipping methods you have configured.

You put some weight restriction and your order is too high.
Please remove the weight restrictions.
