images are not shown in G3, only thumbnail

Hi
I have upload pics, i can see the thumbnail, but when i click on the pic i have this error.

Hey wait, you're an admin! We can tell you stuff.
Ok.. tell me stuff!
Help!

If this stuff doesn't make any sense to you, ask for help in the Gallery forums!
So here's the error:
There was an SQL error: Unknown column 'weight' in 'where clause' - SELECT COUNT(*) AS position FROM items WHERE parent_id = 2 AND `weight` < (SELECT `weight` FROM items WHERE id = 3) ORDER BY `weight` ASC

File: system/libraries/drivers/Database/Mysqli.php, line: 142
And here's how we got there:
