Media uploads unrecognized

Hey guys,

How are you? First post and all. I’d be chippier but I need to get DTB. Right now I’m having a problem uploading media to a site. It’s been replicated both on live and localhost.

The site runs on the Spanish 4.2.2 version of WordPress.

Here’s the rundown:
1) Any attempt to upload media (let’s say, a logo) to the site shows an instant 100% transfer completion message or hangs up.
2) Regardless of what it returns, the files in the media library appear without title, without author, without attachment reference and without date.
3) They are impossible to edit, view, or permanently delete (I don’t even get the option on this last one).
4) The files are in the corresponding yyyy/mm folder and can be deleted there but it doesn’t affect the Media library interface.

Here’s a link to help illustrate

What I’ve tried:
1) Theme(Salient) & plugin on/off
2) WordPress 4.2.2 Dashboard reinstall
4) .htaccess modsec hack
3) Rain dance

Any help would be most appreciated. Hell, I’d be more than willing to buy someone a beer over this.
