object not visible - not a common problem

Ok guys, so here comes the problem: i wanted to applay array modiefier, but there was some problem due to alt + d copy. i did sme fast reserch and find a solution, however inbetween i changed sth, and now the object is not visible in render. Altho some kind of border appered around my object. I find out it is the texture space gizmo or sth, but i cant rid of this. im not sure it is reson why my object is not visible, anyone help? printscreen:
