ItemManager 2.0

[Bigin]

See, there are minor differences between id's, it looks like the values differ on 32 and 64 bit environments. Does your localhost run on a 32-bit?

what questions me most is why by removing everything and recreating everything, the problem remains the same ... it's very curious. 

Unfortunately, you have not yet clearly described what problem you have - once you write you can not access the item data and another time you write that the problem occurs when saving...
