I write a function

f[x_]:=Module[{},(
f::usage="gives the square of x"
x^2
)]

When I run ?f I get a this output:

Global`
CreateUUID["Info-"]
False
False
False

What is the problem? Is it a bug in mathematica ?

Try RebuildPacletData[] and then restart Mathematica. – ilian Mar 17 '16 at 22:56
@ilian, doing that I get this error "Cannot open !("CloudObjectLoader`"). " – BetterEnglish Mar 17 '16 at 23:02
Then a better idea would be to close Mathematica and delete the ~/.Mathematica/Paclets directory. – ilian Mar 17 '16 at 23:25
@ilian, Could you explain why? I can not delete any thing. I have not permissions. – BetterEnglish Mar 18 '16 at 01:42
@ilian, I have already detect a lot of bug's in mathematica, So I am not sure that it is a problem of configuration. It may another bug! – BetterEnglish Mar 18 '16 at 01:43
It is a bug. What I suggested is a workaround. Are you sure you don't have permissions, this location should be inside your own home directory... – ilian Mar 18 '16 at 01:46
@ilian, I found the folder. Could give me what does it do this file? – BetterEnglish Mar 18 '16 at 02:09
