Failed upload in Instagram. Help!

It was perfectly fine until yesturday when I tried uploading a photo and it wouldn't upload. I can still like photos and comment etc. But when I upload something, it would fail. I tried everything possible( turning my phone off (iPhone 5) uninstalling ig and reinstalling it, wifi is good). But it just won't upload pics. Help

Here's the thing… Instagram sucks. I have one and it shuts down all the time and just doesn't work right! So my best guess is that its just IG being crappy again.
