can’t upload files seuddenly

Was this just with 1 specific image or is it happening with all images?

all

What exactly does the error message say?

Failed to transfer the file to /home/onlinebomb/domains/onlinebomb.onfree.co.il/public_html/wp-content/uploads/2010/06.

i dont sure its the exactly message because my blog is on hebrew but its the exact translation

777 is on all files

folder uploads and all files that are therein change chmod to 777, use putty

but it worked perfectly before
can it be something in the host?
