Media Upload HTTP error

Hi there,

When we try to upload pictures we get this error:

polni-dostop-testi-zaslon.jpg Uploading( 100% ) 45 kb ×
polni-dostop-testi-zaslon.jpg HTTP Error. 45 kb

Please help,

Never mind. I figured it out. It was one of the plugins causing an error.

Can you check server error logs and also check it with other plugins disabled and with WordPress default theme.
