Won't let me upload any files at all...

[caps20]

Hello there!

I once again have to ask for your great support here cause I am helpless =) First off, I searched for my problem, I tried everything that seemed to be able to somehow solve it, but nothing helped. I've searched the boards now for over 45 minutes. There are a lot of posts that are somehow similar to my problem but none of them helped me solve it. So...

When uploading any file with HTTP, I get:
The file you have uploaded is not a valid image !
(I get this for ANY image, even images I've uploaded before!)

When adding files with batch add, I get:
Unable to create thumbnail or reduced size image.
File: /home/user and url .../db_input.php - Line: 413

- Permissions are set correctly.
- I use GD, not ImageMagick.
- imagejpeg workaround didn't help - or well, the file had those lines already.

I know it says post a test username/password, but my gallery is actually in the offline mode right now because I need to fix a lot of things, so if it would work without a test user, that'd be awesome. (Otherwise my visitors will get to see the crappy "I'm in the middle of working" stage :])
(If not, let me know.)
I enabled debug, let me know if you need it.

The weird thing is that I was in the process of adding files to an album (via batch upload) and it worked fine for pictures 1-30 until all of the sudden 31 to the last one didn't work anymore. As I said, I even tried to upload pictures I just uploaded an hour ago and it's not working anymore.

Well I hope I thought of everything you need. Any help would be greatly appreciated
Thanks!

Have you run out of space on your server?

That's what I was thinking at first too, but I could still upload files last night so I figured that was fine. Oddly enough, I can't now. I feel really stupid lol. I'll contact my host and see if that changes anything.
Thanks and sorry bout that hah.
