Instagram won't let me comment, like, or follow?

About a month ago, I tried to comment on an Instagram picture and my comment didn't send, and it gave me an error message. I tried to like a picture, and it just went away after a second. This is for every person I follow. Not a specific person. Occasionally it works, but rarely. I logged out and logged back in, and nothing happened. Deleted Instagram and re-downloaded, and still nothing. I updated Instagram and my phone and nothing worked. It's really frustrating because I don't want to make a new Instagram. I've had mine for a while and I don't want to throw away everything. I'm using an iPhone 4 for this.

Go to your general settings on your phone and then> reset all settings. It won't delete anything… Should work.

  • YouTube on my iphone won't let me comment That message I'm the picture appears when I try to comment lately and it's really annoying! What shall I do?
  • Why won't my Instagram let me like photos? I'm trying to like my ex's photo. I have the iPhone 4 iOS 6 but got the new ig update… The ex hasn't blocked me but hasn't talked to me since I put up a wcw as my Bestfriend who is a girl obvi. So I guess she is mad but I'm still following her and she is following me… I can't like her recent photo and I deleted my ig all downloaded it and signed in and the same thing… Why is it doing this to me?
  • Why won't it let me follow this person on Instagram? Well I'm trying to follow this person on Instagram and it won't let me. I'll would click follow, then it will say following for a second, then it would go back to say follow. This person did follow me and I asked them if they blocked me and they said no. I'm doing this on my iPhone 5 and I tried it on my old galaxy s1 and it did the same thing. I'm only following 101 people and I really need help.
  • Why won't instagram let me follow anyone? - 1 It keeps turning to following(green) or requested(grey) I don't know what to do. I've tried deleting the app turning off my phone leaving it for a couple of hours and it's really getting on my nerves (answers please by the way I have a iphone 5c if that helps).
