Upload media error

Hi,
I’m having trouble uploading a wallpaper that is 1920×1080 with only 500kb. It’s way less than my usual wallpaper sizes (2MB) which I had no problem uploading before.

Here’s the error message that I keep getting:
Fatal error: Out of memory (allocated 57671680) (tried to allocate 2304 bytes) in /homepages/38/d112701479/htdocs/clients/Delightful/wp-includes/media.php on line 2108

I checked my DB, i have still over 1GB of storage space. Is this a problem on my server or is this a wordpress thing?
