Image-upload error

I need help. I’ve read Otto42’s post on this question, but I’m just as confused as ever, maybe moreso.

I’m not an experienced coder. I’m a content guy who’s just starting to learn code. So have patience with me.

But in the meantime, I’m banging my head on the following error message when I want to upload an image: “The uploaded file could not be moved to /var/www/vhosts/ocrpl.org/httpdocs/wp-content/uploads/2009/01.”

Just a few weeks ago, the images were uploading just fine in this same version of WP, and suddenly, now, they’re not.

What do I need to do to fix this, and how do I do it?
